Hello. Welcome to Ask The Doctor.
I have read your query. I understand your concern.
As per details, there are following possibilities for your symptoms :
1 ) Allergic contact dermatitis : it is characterised by red colored itchy eruptions over any part of body.
2) Vasculitis- it is usually a bilateral condition characterised by purpuric rash mainly on legs.
3 ) Infection : it may be bacterial or fungal infection.
Treatment depends on the diagnosis.
I would be able to help you better if you could attach photographs of the affected area.
We will revert back in the follow-up.
Wish you a speedy recovery.
