Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it looks like your son suffered from a severe
allergic reaction leading to hives all over the body and as it is clearing off it is a good sign..
Rashes on palms and numb feeling seems to be due to the lingering symptoms only and do not worry as it will also get resolved soon..
He should continue taking the medications and also do cool compresses over the rashes..
In case if symptoms recur you should consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like allergic tests like
Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly..
The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avoid exposure to it to prevent
allergy attack..
The allergist can advise to oral anti allergics as well as injectable
steroids for relief..
Application of
calamine lotion can help in soothing the skin..
Hope this information helps..
Thanks and regards..
