Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, fatty tissue tumour (
lipoma) on shoulder can cause local site pain and
numbness in fingers.
Normally lipoma does not cause symptoms.
But when they enlarge, they cause compression to surrounding structures like nerves.
So pain is indication of enlargement of lipoma.
And this is also an indication for surgical removal of lipoma.
So better to consult surgeon and get done lipoma removal.
Once it is removed, his symptoms will also improve.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
