Osteoarthritis in knee, now a burning sensation in bum cheeks , very sore hip, painful when Sat and get up to walk, now limping with pain. Got X-Ray and doctor happy with it. So what's wrong started 2 months ago. Feel alone like doctor doesn't seem to realise it's so sore. Low at the moment as lost my mum last week. 😢 I'm 51 had lupus since age 14.
