I am exactly like you and I am going to need surgery on my hip eventually!! With the blood, last time I went I found a person there who knew about RSD so she told the one who was taking the blood not to tie the tourniquet tight and that really worked. No pain after (the previous time was a nightmare after blood was taken) I also live everyday in fear of where it will spread next. It totally stinks but I guess you have to think worrying won't change the situation. So I choose not to worry .....some days anyway.

Well hope I helped with the blood test
