What Causes Recurring Bruise On The Same Spot?

I keep getting a bruise, the size of a nickel, in the same spot on my left arm. He is there for a couple days, disappears, then comes back a couple weeks later. It s been going on for about 5 months now. I get other random bruises, but this one is in the exact same spot. Any ideas? Should I be worried?

My Dear

Welcome to Healthcaremagic!

I have reviewed your posting and will share my experience based upon dealing with this problem in good number of cases.

The problem you mentioned seems to be caused by drug eruption known as Fixed Drug Eruption because it tends to occur at the same site every time. some of the common causes for the same are pain killers antibiotics like Sulfa drugs, Tetracyclines. metronidazole, antiepileptics and some others too. Are you regularly required to take any of these?

at times, it could also be due to abnormal response to certain food coloring agents.

Please review your drug intake history and also inform your doctor whenever you visit one that you have such problem so that he or she does not prescribe the suspect drugs

For now, it would help to apply hydrocortisone cream.
Best wishes
