Today is the best my shoulder has felt in a long time. I bought some new ibuprofen not long ago because dr told me to try taking that but only every other day. I already had some but wanted to use it up before I opened the new bottle. Well apparently what I had on hand must have been old and not working anymore. I took the new stuff this morning after my breakfast and I feel not even a tiny twinge of pain in my shoulder today. I don't even care that I have a cold. As a bonus, my headache (from the cold) is gone too.
