I am 62 years old. I am a working woman teaching in a college. My left knee has got swollen on its own from the past few months and due to this my uterus is being pained or vice versa. I am unable to fold my leg. I can not walk properly, stand on right postures. Is it arthritis? I have high bp and taking medicines{tazloc-am} for long. I am done with my uric acid test and its normal. I am taking medicines calcium and febumac-80 from past month. And please suggest some beneficial words. Thank you.
