Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that itching all over the body can be due to
allergic reaction and in case if do not think it is due to blackcurrant soda it can be due to any other food or medicine..
It can also be due to other allergens like any soap or detergent, poison ivy, skin cosmetic etc..
It can also be due to
mite infestation causing Scabies..
I would suggest you to consult an Allergist and get evaluated and he can advise allergic testing if allergy is suspected..
In case if allergy is ruled out he can advise you to take anti allergics like
Benadryl or Levocetrizine, steroids and cold sponges or cold compresses..
An
Immunotherapy can also be given if there are recurring episodes..
In case of Scabies Prethermin lotion can be advised along with Oral
Ivermectin and anti allergics to relieve itching..
Hope this information helps..
Thanks and regards.
