How does it feels to have a lipoma intramuscular? what are the symptoms? is it a serious thing?

Usually asymptomatic: Intramuscular lipomas are usually asymptomatic and are found incidentally. As such, they do not typically require treatment. If it is large enough, it may cause tenderness in the muscle involved (very uncommon). In that case, you should see an orthopedic surgeon.

Might cause: It might cause pain and unusual sensations but nothing else. It can be removed if it bothers you.
