Hello, thanks for your query and welcome to lybrate. I am dr akshay from fortis hospital, new delhi. Please tell me duration of pain and what are aggravating factors? how much distance can you walk and what is the analgesic requirement to carry out activities of daily routine? what medications you generally take and what has been your treatment history till now for existing problem. I also need to see your latest knee x rays so that I know what grade of arthritis are we dealing with on your case? rejoint is not a pain killer but has glucosamine which has been thought to help in cartilage regeneration and minimize symptoms, although its role is controversial. Do not hesitate to contact me if you need any further assistance. Thanks & regards dr akshay kumar saxena consultant orthopaedics fortis hospital, new delhi
