have a poke around the muscle to see if there are any sore spots.
If there are go and get a sport massage to concentrate on that area – percussive type massage tp really ‘smash it up’. Wait for it to recover, using ice, etc.
Then use a grip exerciser or powerball to exercise the muscle and keep it in better shape.
My elbow was in a state a few years ago – had 3 sport massages with the guy really hammering it, and it has been fine since, with a bit of grip exercising every now and again.
Before that I had pyroformis syndrome and a sore spot in my glut – same treatment fixed that – minus the grip exercisers…
