I am 74 years young lady working as Adjunct prof after retirement. I hav been having Back pain for the last 40 yrs. Recently for six months I got knee pain also only on the left where I have back pain for the last many years. Recently in June I had strained for full two days of work of cleaning the entire house from top roof to down using ladder for going up and down. My knee got strained and swelling was there. I had consulted Ortho and took Xray and took tab for swelling pain and all for 20 days. In spite of that the swelling has not come down. I do few simple exercises taught by him/physio just once in a day for 15 mts. Swelling is still there and pain is also while walking but bearable .Now I am not sure whether to walk for 20 mts-long distances and move the leg frequently or whether it wd worsen the situation.. I prepare my food where certain movement or walk is to be done as fridge is outside the kitchen Dr. said that xray is ok and certain degeneration due to age. And asked me not to bother about swelling as it wd go after some time. Can it be due to uric acid which is high in my case as 9.1 .little chlorestrol Trigly, is higher I have started taking febustat Cd you suggest any herbal natural medicine. I stopped all tablets of pain killers and swelling killers. I put Mahanarayan oil on knee and give fomentation but not on regular basis. PL ADVISE whether more exercise and walk wd reduce the swelling or increase it .thanks in anticipation send the reply to my email prof. Hsanthanam@gmail. Com.
