Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain sudden swelling in fingers and ankles along with itching or
Urticaria in different body parts seems to be most probably be due to
allergic reaction to some unknown allergen..
It can be due to a number of things certain insect/bug bites, poison ivy, skin cosmetics, detergents, foods , leather, latex, medicines etc..
It can also be due to
mite infestation causing Scabies..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and blood tests can help in confirming the diagnosis and treatment can be planned accordingly..
You can be advised to take anti allergics like Allegra or Claritin, apply steroid ointment, do cool compresses over the body and apply
calamine lotion..
In case of Scabies you can be advised to apply Prethermin lotion and take
Ivermectin..
You can also be advised anti allergics along to relieve itching..
Hope this information helps..
Thanks and regards.
