Gloucosamine is a supplement and has no pain analgesic value. Its sole purpose is to strengthen the cartilage in your joints. For pain take Ibuprofen and others with care-- Stay away from prescription pain meds and Acetaminophen if you can. I am personally on a prescription pain killer ( read lortab) and am going through hell with withdrawal ( it's a narcotic, up there with morphine and a few others). Before I was put on Lortab I was taking a lot of acetaminophen-- downside to it, liver damage. I would recommend staying far far far away from Acetaminophen…
My approach to pain relief is more holistic, and if you wish to discuss it please let me know.
I hope you find something that works for you,
