Buy the Topricin for foot pain and one can use it on all parts of their body. I keep a stock in my house and now have 3 bottles as I don't want to run out. The foot version is the same ingredients only it's a thicker consistency. It manages and reduces pain, and one needs TO USE IT, and up to 3-4 times daily or more as needed. Can your father take a pain med, I take 1 ibuprofen, 1 extra strength tylenol every 6 hrs and make sure I have food in my stomach. I even take it at 5:30AM as I've got it down to a 6 hr schedule.
