My son had a severe allergic reaction after taking medicine for sudden pain in his leg joints. He developed red, painful dots all over his legs, resembling severe mosquito bites, but without any purple spots. The doctor initially suggested the possibility of vasculitis, but his blood report, including a rheumatoid factor of 8.5, came back negative. I am unsure about the cause of this reaction. Some doctors advise that it will resolve on its own, as additional medications seem to worsen the condition. Please guide me on what steps to take next.
