Hi,Dear,
Thanks for the query to HCM. I studied your problem in depth and I understood your concerns.
Causes-
In my opinion your lump onthe 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 a ER Dermatologits and don't self medicate,as your case has become complicated.
So act fast and get ER Dermatologits consultation and intervention URGTLy.
If you dont want to remove as you are afraid of its pain, then
Show to ER Dermatologits 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 HCM and be comfortable to resolve your health issues.
Welcome for any more query in this regard to HCM.
Write good resume and Click thanks if you feel satisfied with my advise.
Have a Good Day.
