Hi - I Had A Knee Synovectomy About 8 Months

Hi - I had a knee synovectomy about 8 months ago. Doc thought it was PVNS but turned out not to be. Growth was described as a pink fleshy benign mass. Knee continues to be swollen about 90% of the time. I alternate between alieve, Tylenol and Ibuprofen for pain. Recently i added turmeric.
For about last three weeks I feel very thirsty, "prickly" and cold. My knee isn't any better. What do you think?
