Flare up or deterioration
I have moderate hip and mild knee osteoarthritis. I have been struggling with this for about 6 months and have had to stop running. But for the last three months I have been walking a lot and swimming. However last week after swimming I had some inflammation near my hip and related pain in the knee and leg. This hasn’t really abated in the last 10 years, in spite of stretching and rolling and I now find that I have pain after walking a short distance. This seems like a sudden deterioration. Is this likely or could it be a flair up. I hadn’t experienced any flare ups before so I don’t know what to expect.
