Since November last year,I started feeling pain in my knees,specifically when declining stairs.now since last 2-3 months I feel stiffness in my knees. If I be in knee bended position fr few minutes even,like while sitting,I am not able to straighten my knees easily. Around 9 yrs back, I had a problem with my hands'fingers. I could not straighten them when I got up in the morning. All thru the day my fingers were bent.I could not write and do household chores. My ESR was found to be high during that time. I took homeopathic medicines for sometime. I am a teacher by profession.kindly help me out.
