Definitely need to make as many ergonomic adjustments to work station if possible and the motorcycles. Cut way down on any aggravating activities...the possibility of long term /chronic pain is not worth the risk of making things worse..
My symptoms kept moving and changing at first , so i had dx of wrist strain, cubital tunnel, De Quervain's, neck /shoulder strain... docs nor I knew of TOS back then...I learned about it before they mentioned it.. and the advanced PTs knew more about it than the drs I went to. Luckily I was able to start healing with good care and didn't need to seek a TOS specialist.
If you plan to keep working try to find ways to remind yourself to take stretch breaks and maintain posture awareness..
Often I would work and go home and collapse in my shiatsu recliner with ice packs on my forearms and far infrared heating pad on my back- then turn on the massage function after that..
Did you try these at all yet?

foam roll - or large towel rolled up lay lengthwise down spine- rest arms at side..
If you can't do that - then just corpse pose on floor
many times a day..
