<s>[INST] Im a 21 year old male, 58, 157lbs. No notable medical history.I have found a small lump in my middle bicep (Not near any joint) that seems to have appeared after my workout today. It hurts to touch and move, and aside from the lump itself, there is no swelling, bruising or pain around it.It seems like a fascial hernia to me. If so - will it heal?If it isnt a fascial hernia - What might it be? [/INST] HI. Good question>:Facial hernia: gap needs to be stitched, there is no alternative. If this is not a facial hernia, the most probable diagnosis is a sebaceous cyst or a lipoma. Both are painless and non-tender to start with. Lipoma will be very freely mobile but the hernia or cyst will not be. Fascial hernia becomes prominent, fixed and taught if you contract the biceps. Well, a good clinical examination by the surgeon will confirm the diagnosis and will give you the best possible plan. </s>
