Does blood donation cause a lump on the elbow,and if not,what could it be?
Patient: My daughter has a very small round lump in the inner part of her elbow.  She says it feels bruised in that area.  No sign of bruising on the skin though.  Its on the same place where she donated blood beginning of last year.  What could this be?  Regards Tessa Doctor: Hello!Thank you for the query.Yes, skin irritation with needle can cause a lump. Usually it is a fibroma, benign, painless lump which slowly grows. It does not turn into cancer.The best way to find out exactly what she is dealing with, is to remove if and send to histopathology.Please consult a surgeon.Hope this will help.Regards.
