Hello, Thanks for your query. It looks from your details that you are suffering from pain at your knee.Most common reason for knee pain at advanced age is arthritis knee.This can be confirmed by some features which are present in radio-graph or x ray of knee. Medicines which you re taking at present do not help with knee osteoarthritis.To have relief in osteoarthritis knee,you should do following- -Start doing exercises for quadriceps muscles.You may learn this from your physiotherapist. -Start doing warm fomentation with rubber bag over knee for at least 3 times a day. -Take a good analgesic like advil or aleeve. -There are some dietary substances like glucosamine ,chondroitin sulfate,MSM which can be taken OTC.These substances help in repairing of damaged cartilage of knee in early stages. -Avoid squatting movements at knee. -In early stages exercises, medicines ,joint supplements & intra articular injections are helpful & may revert the changes but in late cases joint replacement is only option. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
