Continuous Itching, Painful, Foot, Ankles, Calf, Tiny Bumps, Took Benadryl, Calamine Lotion

Thanks for posting this query. There are a few possibilities for itching on the dorsum of foot, ankle and calf. These include:
1) Contact dermatitis or atopic dermatitis to soaps, lotions, material of socks or shoes. Moreover you have a history of asthma which raises the chances of atopic dermatitis.
2) Stasis dermatitis of the lower limbs
3) Scabies bites caused by scabies mite bites
4) Systemic diseases like liver or kidney causes (less likely)
Treatment is by oral antihistaminics and topical steroids. Oral antihistaminics relieve itching and you can get them over the counter but some of them may cause drowsiness and hence should be taken under medical guidance. Topical steroids is available by prescription from a dermatologist. Then other possibilities like scabies also need to be ruled out.
In addition you can continue to apply calamine lotion which will help in soothing the skin and take some vitamin C which is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
