[|Human|] I have a lump inside my inner arm, where my elbow crease is. It is approx 30-40mm, perfectly round, and somewhat moveable. The lump itself is hard, but it moves a bit inside my arm. It is not on a joint/bone/etc, sort of floating around in the skin/fatty area on the inner part. It is painful to the touch, feels similar to a bad bruise. I haver had any trauma to the area that I can think of (though I am active with my 2 and 4 year old so it s possible). It s appeared in the past 48 hours and is becoming slightly more painful (slight numbness on that area of my arm). Help! Any ideas? No health issues, female 32 years old.
[|AI|]  Hi, dear. I have gone through your question. I can understand your concern. You may have some enlarged lymph node, benign cyst, lipoma or other soft tissue tumor like neurofibroma.  You should go for biopsy of that lump. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
