I can't diagnose via this medium I'm afraid but you may have some inflammation of the tendons, something a physio or MRI scan via your GP will confirm.
Knees can be hard to treat, so please consider combining the short-term effects of our Atrogel®: with the longer-term effects of out Atrosan® tablets.
Above all though, get a diagnosis so you know what you're dealing with.
Best wishes
