You should have the orthopedic surgeon who performed the arthroscopic exam determine the cause of the problem you are describing. It’s possible you have a superficial skin infection. Or you may have the beginnings of a problem called complex regional pain syndrome (CRPS). Either way, early diagnosis and treatment is essential.
Skin infections are usually treated with topical and/or oral antibiotics. The symptoms clear up quickly within the first few days of taking the medications. Something more complicated like complex regional pain syndrome (CRPS) is not so quickly or easily treated. CRPS has various stages that last varying and unpredictable lengths of time.
Treatment depends on the symptoms and may include physical therapy, acupuncture, electrical stimulation, nerve blocks, and medications. The medications may be used for pain control, to improve circulation, or to interrupt nerve signals causing the painful symptoms.
Your physician is the best one to guide you — first in determining the correct diagnosis and then in providing a plan of care. Don’t hesitate to go in for a follow-up appointment as soon as possible.
