Large localized red itch welts

[masson]

I thought I was bitten by a mosquito,  but got home and found that I had 4 quarter sized large red itchy razed welts on my lower buttock and a larger 1/2 dollar one with a smaller one next to it (about the size of a penny) on my right upper back thigh. I had been to the gym, showered put on shorts and walked home. (During this time, things started itching, hence the mosquito thought) The itching was BAD during the night and still itches now. Any help would be greatly appreciated.

Thanks for your answer. I got some cortisone and am putting cold compress on the welts...no spreading, but ITCHY!! they are raised and hard (not rock hard, but not like the surrounding skin) no pain...just itch. They blanch when i press on them...quickly, but they blanch.... One is rather large with a smaller one beside it....frustrating. As i said in my other post, i don't have insurance and really don't want to go to the emergency room....

Hello,
I cannot confirm anything without examination but it can be hives,sweat dermatitis or fungal infections. The mainstay of treatment is antihistamine which may be necessary for prolonged periods .You can take non-sedating antihistamines such as Cetirizine or Loratadine to get symptom relief. Short courses of oral cortisone or steroids are taken for short periods (one to three days) to settle more severe symptoms. Application of calamine lotion will help in soothing the skin.
If the symptoms persist then please consult a dermatologist.
I hope it helps. Take care and please do keep me posted on how you are doing or if you have any additional doubts. Kind regards.
