Took Motrin And Benadryl For Mild Cold. Noticed Broken Capillaries All Over Body. Should I Be Concerned?
As rightly mentioned by your treating physician it could be viral.
What happens actually in viral infections is that the immune system forms complexes with viral antigen.
These complexes can do following two things .
1. They can destroy the platelets and cause purpura.
2. They can get deposited in small vessels and cause vasculitis.
As you had burning pain and that too more in legs, probably it was vasculitis. The treatment of choice is prednisolone which you have already taken. Dont worry about the pain. In vasculitis pain persists for few days even when lesions are gone. It will decrease with time, although not completely, as you have sciatica.
Immune system overdrive wont affect just one nerve. So please don't worry about that
For now you dont need to do any other test. If you get similar lesions again get your XXXXXXX profile done. As vasculitis sometimes happens, only in XXXXXXX susceptible individuals.
Hope I answered your query
Thank you
