I donated blood Friday and later that night I went to a rave and I drank alcohol and got pretty buzzed later at the rave I noticed a bump had developed where they inserted the needle to withdraw blood from me and this bump has hurt and caused sharp pains well it Burns occasionally and when you touch it it feels hard can you tell me what s wrong with my arm?
Hi, Thanks for using Chat Doctor, It is good that you donated blood, for taking blood from vein a large bore needle is used hence after completion of donation process a firm pressure is required for sufficient time to close the vein puncture. It is possible some blood has leaked from the site and deposited in subcutaneous space and inflammatory reaction has developed to cause pain called Thrombophlabitis. This not a serious issue you can apply ice fomentation to get relief and if there is coloration around it there are gels available of heparin can be used locally to expedite recovery. You will recover with this problem in few days do not worry at all. Hope this helps. Take care. Good Luck.
