I have had surgery on my knee around 17 years ago, an adjustment was made under my kneecap and debris cleared (keyhole surgery) in the last 6 months the problem has reoccurred. I am taking anti-inflamatories but now my ankle and foot are swelling and my skin around that area is blotchy and itchy, I've had an x-ray on my ankle and foot but no bone damage, getting frustrated with the swelling, what should I do?
