I know what you mean. I had brain surgery transsphenoidally (through the nose) and the recovery pain was like the worst sinus headache x 1000. Only morphine shots provided relief. When I left the hospital both the pain and the withdrawals were horrible. Thank goodness I do not have an addictive personality. We still have strong pain medication from some procedure or other from a few years ago (probably expired by now) in our medicine cabinet. I don’t enjoy opium’s “high” at all.
I wish you well.
