I had blood work done today (1 vial, to test for iron deficiency). The site (left arm) never before bruised, but today, after several minutes of applying pressure (as directed), the vein was swollen, bruised and red spots (like blood spots) appeared under the skin. That was 6 hours ago. It now has grown to nearly an inch long, is both itchy and minorly painful. The nurse did not ask if I had any allergies (I do, to latex), and I wonder if that is the issue? My left hand hurts a bit as well, a dull throb (this is not normal). Should I be concerned?
HI, thanks for using Chat Doctor The discoloration may be related to injury to the veins and surrounding soft tissue. This would resolve on its own. There may be also some allergy as well since the are is itching, especially is the latex was used. Using an oral antihistamine would help. These are available over the counter. I hope this helps
