"i can exercise now in less pain.  make sure you get the correct dosage that you feel comfortable with. if you take too little of a dosage, you may still have pain and lose hope in the medicine. it happened to me. i ended up doubling my dosage from 300mg to 600mg a day and feel so much better. i take 300mg twice a day as needed. i was originally on 100mg a day and it did nothing for me. most people start off with 300mg."
