No did not help made it worse.

For tight muscles, stretch before and after exercise. Hold the stretch for over 30 seconds, and you will get a deeper stretch.

Every day.

Don't discount the value of stretching both before and after exercise. Since I'm not disciplined enough to do it myself, and I can afford it, I hired a guy who could doubtless bench press twice my weight, to manhandle me once a week after putting me through a workout ... as the product of six decades of being a body-neglecting brain-in-a-vat, I was so tight and knotted up that I don't think I could have undone it any other way. Although I had to learn to disassociate from pain in new ways during the actual stretching, it really mitigated the after-effects of working out.

Then I was just left with core strength and balance issues to address. As my trainer said, rather too gleefully, "I'm going to spend the first six weaks breaking you down and then we'll start building you up."

Damn near killed me but I'm the better for it. I think. Time will tell, I'm not quite through the "breaking down" phase yet.

I had a frozen shoulder for awhile a few years ago, and that was basically a matter of stretching too ... running it in circles and damn the pain, and after about a month of that it was nearly good as new. After three months I had full range of motion and zero pain. But you have to hurt yourself to get there.

No Coral but I had a tens unit which uses electrical shock and works. You can buy them over the counter not like Icy hot.
