[|Human|] A while ago I noticed a small lump/bump in the crook of my elbow of my let arm. It is painless and when I touch it it is soft and moveable. It is unnoticeable unless I extend my arm, and even then it is only noticeable to me. Recently I ve noticed that there is also one located in the crook behind my left knee and also two under my right armpit. What are these? Should I be concerned?
[|AI|]  Hello! Thank you for the query. It may be a lymph nodes or lipomas. In case of lymph nodes, lumps should be hard and rounded. If these are lipomas the structure should be soft like a fat. You should be concerned only if you have lymph nodes enlarged in these areas. If so, ultrasound should be done at first and biopsy considered. In case of lipomas, you may leave it alone and watch or consult general surgeon and have them removed. Hope this will help. Regards.
