I'm wondering if anyone else has noticed anything like this.

When I extend my arm and angle my wrist down, and lightly run my other hand over the top of my forearm, I can feel little lines of bumps.
seems like they are running along the tendons or maybe the muscles...

I haven't had a dr check it yet, just a weird thing and I wanted to see if anyone has this also. No pain with it, if anything maybe a lingering minor tightness.

Might be Tendinitis, tendinosis or Tenosynovitis - or just some other strange thing LOL.

I did have severe bilateral wrist/arm problems in 1999, my first injury, work related..
