Thanks for the query
If your question is whther the initial diagnosis was wrong then i think it is highly unlikely because u did have hallucinations
and it definitely improved after taking the medication and it looks like u r in relapse now after stopping them. It is a little risky to stop the medications on your own a=
If your question is since you are 37 is there any other cause for your bodily pain then yes it is possible that there might be another cause for the pain. In either case please see your doctor and dont take independant decisions.
Have a healthy living
