Hello, Just stumbled across this website when trying to google info about lumps found on arm area. Have found a hard lump about the size of a large pea on inside of lower left arm 2cm from elbow crease. Have also recently noticed during aerobic stretches that I am unable to straighten left arm. There is also a noticeable ache around the elbow area of left arm. Is this a common occurrence? Please can you offer any advice but no worries if there are more important questions to answer, I understand if there is no time to reply.
Hello! Thank you for the query. Arm appearing while exercising close to a joint can be a ganglion cyst. Such cyst is usually connected with a joint and filled with joint fluid. When performing an exercise, this cyst can get larger and more visible. I suggest you to consult orthopedist with this issue. Elbow ultrasound should be done. If its ganglion cyst, should be removed. Hope this will help. Regards.
