<human>: I have a lump on my arm situated between my elbow and wrist.  It is painful to touch and quite hard, slightly bigger than a pea, I noticed it about 4 days ago and first thought it was something like a blind spot but it seems to be getting bigger.  Should I be worried?
<bot>: Hi. Thanks for your query.A swelling just bigger than a pea, growing in size and has pain in a situation between the elbow and the wrist can be due to the following:Most probably infected boil or so. Lipomas do not usually cause pain at the size you have mentioned. I would advise you to take a course of an antibiotic and anti-inflammatory medicines like Ibuprofen for a few days. This may resolve your problem. If not resolved, consult a Doctor, preferably a General Surgeon, get a diagnosis and get treated accordingly.
