I am on dialysis and use both my cvc and my arm for dialysis. my fistula is not developing as well as the doctor has hoped. I have had additional surgery to tie off some veins in my hand. Last week, a nurse went to use the fistula but went too low and it seemed to hit some scar tissue. Immediately, it was hurting and the nurse removed the needle as my arm had swelled up. One of the nurses gave me a cold compress to put on the site. several days later, my arm started bruising. my arm was hurting for the first few days. It no longer hurts, but I have this ugly bruise approx. 4 inches long by 2 inches wide. I have put cold compresses on it at home, but sometimes I forget. any way to speed the healing process up?
