Jim,I have same problem with right shoulder/back.
I solved the problem until I heal up,which is
happening. I bought a used left hand Hoyt bow on E-bay $61.00.The seller turned it down to 36# and I am learning to shoot left hand. In mean
time to insure I can hunt this Fall ,I purchased
an Excalibur Phoenix crossbow.It's fun to shoot and very accurate. I should be multifunctional
if I heal up.
