Hi all I picked up the bass for the first time or 7 or 8 years about 10 days ago and I have been playing a couple hours a day I guess. I also have a degenerative neck issue and a numbing and heaviness feeling of my arm as a result of that. This week the interior muscle of my forearm on the inside feels like it is strained and tight and I cannot reach the full distance with it. I don't know what that muscle is called a but it is the meaty part on the inside of the forearm not the outside. I am wondering if this is a result of my playing or just my neck issue acting up. I have been playing in a sitting position using a floating thumb technique and trying to keep my wrist straight and doing not quite as much with a pick. For that matter my fretting hand on the inside seems to be over worked too, but I surely can attribute that to not stretching last week before playing. Are interior forearm muscles soreness common with bassists? I've never had it before. Thanks!
