I have chronic back and leg pain from arthritis(I guess) and inflamation, also from a small herniated disc(l-4,l-5) Also hip pain and stiffness that prevents me from walking normally almost 80% of the time, particularly if I've been sitting for more than a few minutes.I've had steroid injections that relieve the hip pain temporarily. I have used large doses of ibuprofen, aspirin and/or tylenol with almost NO result. Even Lortab does not resolve my pain completely. I recently tried Doan's just for the heck of it, and I seriously though I must have died in my sleep, as I woke up virtually pain free with just one dose. Is it more likely to cause kidney and liver damage than ibuprofen?? Can you take it every day??
