I had blood drawn a few weeks back. Normally there is no pain, this time it was very painful and have had tattoos. Instantly my vein in my arm bulged to the point i could clearly see it and touch it raised. It was very hard to the touch, i told the nurse who said nearly finished. After finished there was no excess bleeding just very sore. Since then i have constant pain, no strength to even open a pill bottle, tear open a bag of chips ect ect. Any idea what could have happened? Thanks
