Thanks for your question on Healthcare Magic.
I can understand your concern.
I don't think you are having Angiolipoma. Angiolipoma is benign tumour consists of blood vessels and fat tissue.
This can not cause such kind of severe agonizing pain.
Angiolipomas are almost always painless.
So in my opinion, you should consult another doctor and get done clinical examination and
Biopsy of this swelling to confirmed the diagnosis.
You will need surgical removal removal of that swelling. And yes, they can recur in same site or in other parts of body.
Don't worry, you will be alright.
But better to first diagnose yourself.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
