Hello. Please I need advice and help. I had an i.v infusion at my emergency vein at the vein above my elbow, about a month ago. But to now I still feel burning sensation in my the muscles at my elbow and above my elbow (that is back of the emergency vein area) I don't know if I suffer from extravasation or if it is something else. I also suffer from staphylococcus aureus infection. That I took the i.v infusion for but the staph didn't go. I don't know if extravasation last that long or if it is my staph that is causing the pain I need help! Is there a scan I can do to detect if my nerves are been damaged. Or should I just consider staph as the cause of it?
