19 lymph nodes is a lot! Could it be lymphadema? I would have it checked. Have no idea if crocheting would be related. Wish I could do that! I could make a mean chain, though! Think there may have been a headband or two, in both knitting and crochet, but that was about as far as my talent went. Being left handed, I never found anyone who could really teach me, and doing it "backwards" just didn't seem to work.
Is all going well otherwise? Good to see you post... wish it were under different circumstances!
