Hi, I tried to donate blood two days ago, but they missed my vein three times and it hurt way more than normal, they had to quit try and I didn't even donate. The entire time since, I have had this painful sensation in my arm, not directly at the injection spot, but rather one to two inches below it. At first it felt like a cut opening up again, but when I took off my bandages, that wasn't the case. It kind of feels like my forearm is being hit with little rubber bands multiple times. I can't extend my arm, in any way, without this happening. Why is this happening and how do I get it to stop?
