Can anyone help,
I've been having this pain on my left forearm, that comes and goes. I notice on the same arm that my veins look a little swollen and that there was a lump on my vein just under the skin. I am on heavy pain killers from a back injury and I'm not sure if that may be the caused since I been on the medication for over a year now. It doesnt hurt when I touch it but it aches pretty bad. Its not sore it just aches.Can someone help.
