Hey Wearepeople,
Weird experience bro. Just wanted to chime in cuz I was a Massage Therapist until one of my shoulder muscles detacted from the bone and rolled up somewhere and ended that career.
But I wanted to give you a suggestion if you can't get to a good Massage Therapist. Try taking a 15 minute Epson Salt bath in hot water. Make the water as hot as you can stand it. That will help with muscular tightness. You can get epson salt at Walgreens or any drugstore....and it's cheap.
After a nice hot epson salt bath, you could give it another go....pain free!
Hope that helped....
