sound like the Dr has given you quiet a definitive diagnosis.

from my understanding a lipoma usually lies quiet superically under the skin, so excision of the lipoma should not affect any nerves.
on your 1st post you said that no nerves were cut.
on your last post you said the dr tore the nerve on excision of the lipoma.

How big was the lipoma?? you must have been very lucky, or should i say unlucky to fall directly on to the lipoma. (no disrespect to your doctor)

if taking a deep breath causes pain, then it may still be musculoskeletal. i would be inclined to get it checked by a physio. not too sure how its works where you are ian, but in Australia you can go straight to a physio without a doctors referral.

sorry to sound narky. would love to be able to assess your spine.
