I am 28 year old. I had knee pain in both my legs and elbow pain in my left hand. I had consulted a local orthopaedic doctor. He prescribed me tablets NUROKIND LC (15 tablets), NEORELAX MR 4mg(10tablets) and it got cured in 2-3 days. He had written my problem as polyarthralgia in the doctor's slip.    After few months again the same problem has reoccured so what actually is my problem?? how can I cure it naturally without taking medicines?? Is it my problem has occurred bcoz of weak bones or muscles or nerves?? Will it keep occuring again and again like arthritis problem of old people??
