What causes swelling and numbness in the knees after an accident?
Patient: I was in an accident almost six weeks ago on a scooter where I hurt my knee there was a deep scab and bruising and it felt numb for 4 weeks. I had acupuncture on the knee which seemed to irritate it and now it’s swollen up like water on the knee but it doesn’t hurt unless i bump into something. The feeling has returned also. My question is does this swelling seem like a normal part of the healing process after it being numb. Doctor: Well come to HCMThank for asking to HCMI really appreciate your concern, I could say that the given condition could be due to accumulation  of blood (Hematoma ), imaging study can confirm the condition if this is so the it may resolve on its own but care needs to be taken for infection, it is not the normal condition, but as long as the differential diagnosis is concern it may be something else than the blood collection, it may be abscess formation, it may be escaped synovial fluid, better to see the orthopedic surgeon    hope this information helps
