FYI, numb finger tips can also be a sign of nerve damage due to repetitive motions and a lifetime of use. So it may not be archery per se that caused it, but archery sure might be exacerbating it!
I have a pretty bad after 30-years of drumming and always having hobbies that extensively worked/used my hands. What works for me is exercises that uses the fingers in the ‘opposite’ motion, like putting an elastic around your fingertips and spreading them wide open, exercising the extensor muscles. In daily life, everyone ‘grips’ things, predominantly using the flexor muscles, but if muscles aren’t in balance, that can cause problems too.
There is a condition where the sheath that the tendon goes through in your forearm, akin to carpal tunnel of the wrist, can cause or contribute to the tingling or numbness. I went to a good orthopedic Dr and got hand/forearm stretching exercises that has really helped me! Like putting your hand up like a ‘stop sign’ and pulling back on your fingers and doing your long repetitive stretches can definitely help!
