[|Human|] My son had itchy welts on one of his outer thighs and they went away. He also got them on the other thigh on a different day. He also said he had a wierd sensation on both of his hands. He then said that he had a lump on the bottom of his foot that he could not walk on it but that went away too. Could you explain any of this?
[|AI|]  Hi, Dear,Thanks for the query to Chat Doctor. I studied your problem in depth and I understood your concerns. Causes-In my opinion your lump on the foot /hands / thigh are due to Acute on Chronic Idiopathic Urticaria, and needs ER Dermatologist consultation and treatment. Many cause for CIU needs to be ruled out and treated accordingly. Your son has very sensitive and labile immune system currently due to many factors and causes inside the body, which needs to be studied and treated by ER Dermatologist accordingly. So you need to take treatment under cover of an ER Dermatologist and don't self-medicate, as your case has become complicated. So act fast and get ER Dermatologist consultation and intervention Ugly. If you don't want to remove as you are afraid of its pain, then Show to ER Dermatologist if it grows and worries more. So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you, but just ask a query to Chat Doctor and be comfortable to resolve your health issues. Welcome for any more query in this regard to Chat Doctor. Write good resume and Click thanks if you feel satisfied with my advice. Have a Good Day. Chat Doctor. N.
