Following a blood test this afternoon my arm became very sore and swollen. I do have tiny veins but the puncture and test went well. It was immediately afterwards while the tourniquet was on that the discomfort and swelling started. Several hours later it is still swollen and sore.
Hello, I read carefully your query and understand your concern. The symptoms seem to be related to the injection. I suggest using anti-inflammatory medications such as Acetaminophen to relieve the pain. I also suggest using cold compresses at the injection site. The symptoms will relieve gradually. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
