I am allergic to musquito bites.It cause itching pimples around the area of bites which last fr days.Is there any way to improve immune towards bites?

Insect bites: I assume by mentioning a way to improve your immune system toward mosquito, you mean allergy shot for mosquitoes. It looks like you have large local reactions to mosquito bites. If there are no systemic reactions like hives, difficulty breathing, belly pain or other GI symptoms, we usually don't check for allergy or try to desensitize you to mosquitoes. You can try otc topical cortisone as needed. ...Read more

Are there mosquito bites that do not itch? I have a bug bite , same size as mosquito bite but it's not itching or turning into a blister

Yes but: The very first mosquito bite may not induce itching but subsequent ones will since one then becomes allergic to the components in the venom. Not all insect bites induce itching (spider bite for example) . The odds are against a mosquito bite not being itchy and thus the bite was likely from another insect. ...Read more

Can a rash from scabies spread after permethrin treatment of the mites are killed? Just did treatment last night, rash on cheek now, not itchy

Probably not but: Even if the mites are killed, they have left some droppings behind in the skin areas where they had visited. The allergic reaction to the droppings may linger on for a couple of more weeks. However it is uncommon to involve the face and thus the problem may not be scabies. ...Read more

Tick bite continue to itch 4 mos after bite...took doxycillin immed after bite "just in case." No other symptoms, no evid of tick borne illnesses or cellulitis. Piece of tick still under the skin?

Tick bite continue to itch 4 mos after bite...took doxycillin immed after bite "just in case." No other symptoms, no evid of tick borne illnesses or cellulitis. Piece of tick still under the skin?

Good question.: No risk for tick borne illness here. Is there any type of rash at the wound site? An embedded part of the tick would fester a little under the skin and may become a little red and painful until the skin pushes it out or it's broken down. If you have been washing it over and over or scratching it I'd say eczema, neurodermatitis or scabies it possible without any other rash or lesions. See doc. ...Read more

Do mosquito bites after itching turn into white heads? Does that mean they got infected?

Mosquito bites: They normally do not turn into white heads. What you describe means there is some type of local infection, likely due to scratching. If there is also redness and tenderness you will need some antibiotics, see your doctor for evaluation. An interesting side note, fire ant bites which are common in Houston do get a small pustule like a white head, so it is possible you have those. ...Read more

Multiple welts on lower legs and up to elbow. Almost like mosquito bites but sting more and don't appear to be bites. Any idea of cause?

Multiple welts on lower legs and up to elbow. Almost like mosquito bites but sting more and don't appear to be bites. Any idea of cause?

A couple of thoughts: First, skin problems can not really be managed without a visual..consider uploading a picture to HealthTap virtual consults. Painful welts can be a condition called erythema nodosum, but it would be unusual on the forearms, & usually occurs in younger women. Urticaria can result from an allergic reaction, but is usually itchy. Would favor inflammatory over infectious cause. See doc/Dermatologist. ...Read more
