Pretty much all sports injuries are best treated with RICE = Rest, Ice, Compression, Elevation. This was true true when I was a kid and now, after 15 years of youth sports.
Doctors and sports chiropractors often tell us to take advil also when nursing an injury.
All seeking to reduce swelling and pain.
I have heard “always ice, never heat” for injuries in younger people and alternate ice and heat for older people.
Knowing scaredy isn’t a “young person” I think you might try heat first, then ice. Heat loosens things up and ice to kill the pain. Advil would probably help alot.
My dad swore by glucosamine for joint pain, He died at 87 and never took vitamins or supplements or bought into any “alternative” medicine. Until he took glucosamine. He said it worked and recommended it to everyone who ever complained of joint pain.
