If you aren't an active person, jumping into an intense activity is almost always going to do more harm than good. That said you should employ other forms of therapy like heat/cold, compression, elevation, and, yes, light activity aimed at the area. Also bring up trigger point injections with your doctor if this is an ongoing issue.

It must be true if you read it on the internet. Try it again to be sure it won't work.

webMD, not. even. once.

What better doctor than internet trolls
