i hit my elbow very hard at work the other day and a bruise formed around my elbow and in the middle of the bruise it stayed white and had a lump in it the bruise is almost gone but my arm goes numb and in the morning my hands are swollen what could it be?
Hi, Most probably it is due to minor nerve contusion this can happen after blunt injury. Consult a physician and plan for an MRI scan. As of now you can take Vitamin B12 supplements for symptomatic relief. Hope I have answered your query. Let me know if I can assist you further.
