Sorry you have so many health problems. Welcome from the Sacramento area in Northern CA.
There are quite a few members with assorted ailments and everyone works at their own pace (it's not a race) and I bet you will get some ideas for easing the relearning process. I just found out that I have carpal tunnel. The therapist told me that I need to stop quilting if it makes my hands hurt. I laughed at her - she didn't like that.
WHere there's a will, there's a way and you have the will.
