It's the first time I've donated and although it didn't hurt, my arm looks pretty gross now. When I took my plaster off, there was a small bruise, however when I woke the next morning, it looked bad. There are three quite large, dark purple and black bruise. There is also a bit of a lump in the vein above the needle hole, and when I run my fingers over the vein above and below, it doesn't feel right. The hole is still pretty tender too. My arm and the bruises don't actually hurt, it's just tight. Only the hole is slightly sore. Is this normal? Should I be worried? Thanks.
