The most unfavorable and dangerous complications and consequences that develop after a gadfly bite include inflammation, swelling, and allergic reactions. The most dangerous condition is Quincke's edema, anaphylactic shock, asthma attack, and exacerbation of bronchial asthma. There is also a danger that a bacterial complication may develop, suppuration when the infection enters the body. When eggs and larvae enter, a parasitic disease develops.

How long does a gadfly bite last?

It is impossible to give an exact answer as to how long a gadfly bite will last, since the reaction that develops is determined by the individual characteristics of the organism. It depends on genetic factors, the state of the immune system, the level of sensitization of the organism, and even the current state of the organism, for example, on what diseases the person has suffered, how long ago he took various medications.

In general, if the body is in a "normal" state, the average person's bite will go away in 3-5 days. However, if a person has recently been ill, or has an overly tense immune system, or is prone to allergic reactions, the bite may not go away for even several months. The doctor can tell you approximately how long it will take to treat, but he will need laboratory test results for this.

Allergy to gadfly bite

If a person has a history of allergies, hypersensitivity, asthma, an allergic reaction to a gadfly bite will inevitably develop. The degree of its severity is determined by many factors. First of all, it is the type of reaction. So, if a person has a tendency to develop HR NT (immediate type reactions), [ 1 ] the most severe and life-threatening conditions develop - Quincke's edema, which causes abrupt suffocation, anaphylactic shock, which causes a critical drop in blood pressure and body temperature, suffocation. A person can fall into a comatose state, or even die.

More favorable is a delayed-type allergy. In this case, in response to a gadfly bite, a predominantly local reaction develops, which manifests itself in the form of swelling, redness, and itching. In this case, it is enough to take an antihistamine (suprastin, diazolin, loratodin, loran, etc.). Locally, the bite is treated with ointments and gels. Folk remedies are also used.

In case of an immediate reaction, emergency assistance is required. If anaphylactic shock occurs, intravenous calcium chloride infusions are prescribed (10 ml of a 10% solution). It is also recommended to give injections - 2 ml of a 0.5% solution of novocaine and 0.1% solution of adrenaline at the site of the bite. After the threat to life has passed, you should consult a doctor.

Why doesn't a gadfly bite go away?

If the gadfly bite does not go away for a long time, you need to contact an infectious disease specialist and get tested for the development of a parasitic disease, the presence of larvae under the skin. Even if the diagnosis is refuted, appropriate treatment will be prescribed. If necessary, differential diagnostics are carried out, which will allow you to differentiate the gadfly bite from the bites of other insects.

Any gadfly bite is associated with the development of an allergic reaction. This entails itching, which can be relieved with antihistamines. In addition, if severe itching bothers, antipruritic agents are prescribed in the form of local ointments. Not only local, but also systemic agents are prescribed, such as strengthening, restorative, immunostimulating agents. They strengthen the immune system, increase the overall resistance and endurance of the body.

Various essential oils are used to prevent and treat gadfly bites. They cannot be used in their pure form, so they are diluted in base oils for massage (2-3 drops of essential oil per 40-50 grams of base oil). Apply to the bite site. Oils such as rosemary, lavender, juniper, lemon, spruce, fir, and eucalyptus have proven themselves well. They quickly relieve itching, prevent inflammation, allergies, and prevent infection and parasitic invasion. [ 2 ]

Traces of a gadfly bite

You can recognize a gadfly bite by the characteristic mark it leaves behind. It is a small dot, a puncture in the skin. Around it, redness, slight swelling of the skin, edema, and severe itching almost always form. However, there are cases when edema does not develop.

Usually, after treatment, the mark disappears completely, leaving no scars. In any case, you need to visit a doctor who will examine the bite and make a diagnosis. In this case, differential diagnostics can play an important role, which is based on the need to differentiate the signs of various bites that have approximately the same external manifestations. In addition to a visual examination, additional laboratory and instrumental studies may be required.

Complex therapy is mainly used, which includes both systemic drugs and local ointments and creams against itching, swelling, and inflammation. Special creams, ointments, and gels are applied, which can be purchased ready-made at the pharmacy or prepared at home using an available recipe. In order to quickly relieve swelling, diphenhydramine is used (0.025–0.05 mg orally). [ 3 ] There are also a large number of combination products, which include various non-steroidal drugs, such as aspirin. [ 4 ]

Skin rash in the area of the gadfly bite

A characteristic feature of a gadfly bite is redness and swelling. Skin rashes can develop in a person who is prone to dermatological diseases. But this is rare and usually occurs some time after the bite, approximately 5-10 days. A gadfly bite can provoke an exacerbation of existing skin diseases.

After a gadfly bite, swelling and redness

Redness develops immediately after the gadfly bite. But swelling can develop after 5-14 days, and this is usually an unfavorable sign. This may indicate that the bite site has been infected and an inflammatory process is developing, [ 5 ] or that larvae have entered the body. [ 6 ] In both cases, immediate qualified assistance is required. Self-medication is prohibited under any circumstances. You need to see a doctor as soon as possible. If possible, an infectious disease specialist, parasitologist or bacteriologist. If there are no such doctors in the clinic, a therapist will be enough, he will give the necessary referral to the necessary specialist. Perhaps a surgeon will help, or a consultation in a specialized infectious diseases hospital will be required.

Itching at the site of a gadfly bite

There is nothing surprising or unnatural about the fact that a gadfly bite itches. This is a completely natural reaction, since an allergic reaction develops after the bite. A large number of antibodies, histamine, can cause itching and other symptoms that develop mainly locally.

Treatment consists of preventing the development of an inflammatory, infectious process and severe allergy. If the bites itch, then first of all, you need to drink an anti-allergic drug, and also smear them with a special anti-itching agent.

The main anti-allergic agent is suprastin. It is taken 1 tablet 2-3 times a day. Suprastin has one significant drawback - it can cause drowsiness and a slow reaction. Anti-inflammatory ointments, as well as anti-itching and anti-allergy ointments, also help well against bites. Steroid and non-steroidal anti-inflammatory drugs are used. The following ointments work well: diclofenac, ibuprofen, indomethacin, naproxen.

Swelling from a gadfly bite

A gadfly bite can cause swelling, and this happens in most cases. Most often, complex treatment is prescribed, which includes both medication and local remedies. The bite site is treated with an anti-allergic and anti-inflammatory agent, or a special antiseptic. An excellent addition to standard therapy is compresses, lotions, baths and complex medicinal baths, taking stimulating balms internally.

Bruise from a gadfly bite

A bruise is a rare occurrence. A gadfly bite often causes swelling, redness, pain, and burning. A bruise (hematoma) may be a consequence of compression or damage to a small blood vessel, a capillary, which causes bleeding under the skin. A similar reaction also occurs with severe swelling, which affects the vessel. It is necessary to take measures aimed at eliminating swelling and removing the hematoma. Bruises usually appear 3-4 days after the bite, not earlier. Baths, compresses, lotions with the use of various medicinal decoctions and infusions help well. You can take immunostimulants internally.

Temperature from a gadfly bite

An increase in temperature from a gadfly bite indicates that a systemic reaction is developing in the body, in which the inflammatory and infectious process affects not only the bite site. The reaction is generalized throughout the body. Comprehensive treatment and mandatory consultation with a specialist are required. The danger is also that infection may occur, or a parasitic disease may develop (larvae have gotten under the skin).
