good for you getting PT. Definitely check with an OT on your sewing set up. I have shoulder issues, have had surgery on one, and have to make sure that I'm not doing the same thing (sewing vs. LA vs cutting) for too long our my arm gets numbness in hand---all related to shoulder. I had my son cut down the sewing table so my elbows are at right angles. I can also put my travel machine on my cutting table and stand--it takes a bit to used to sewing that way, but I really do think it's easier. And my cutting table is an adjustable drafting table so it's high enough that my elbows are at the magic right angle. I'm trying to do a better job of using my drafting stool at the LA (knee issues) and bring the work to me instead of stretching. And one thing I would recommend if you don't have it yet is an electric Accuquilt Go! it has saved me lots of pain.
