I had back fusion 7weeks ago and still in pain is this normal. Still can't sit upright for long either. Thanks?

Back pain . Back related diseases can be very delicate do deal with. Particular back surgeries do not necessarily resolve any back pain issues completely. There could be even more of a problem with any surgeries performed. For example the lumbar area of the back contains a highway of nerves. Any minute mishandling of these nerves in any way can produce different degrees of pain.
