Yes...I got the sheet of exercises too, and even some bands to facilitate the work.
But even with that, it didn’t take long. I think it is because the problem wasn’t one injury, but ongoing arthritis.
Once my issues progressed beyond that, I ended up taking Indomethacin when my problems flared up. That's normally prescribed for gout, but it did the job when I had a problem.
You may need something stronger than over-the-counter pain remedies.
