HI.
Thanks for your query and an elucidate history.
Since all the tests are normal you are a patient of
IBS for sure.
The proper treatment is as follows:
Treatment:
''STRESS'' = stress is the most important cause of IBS. Please remember and you must have observed that when you do not have stress your problem with IBS is reduced
Change of lifestyle.
I think 'may be' you are not coping with something.
Vacation outside of your area, mobiles phones to be off.
You must have noticed already that these changes help a lot.
Try to avoid anything which you are / have to do against your will and wish. Getr into the hobbies which make you forget the world around you. Life comes only once, boss.
If the change of routine helps, the necessity of medicines is drastically reduced to almost nil.
Medicines ::
You need to have a prescription of a Doctor, please discuss this with a Gastroenterologist to get a prescription. I would like to know which medicines have you taken in the past and in which dosage
Vit A and Vit D in therapeutic doses,
Multiviatamins ,
probiotics,
anxiolytics help a lot.
Pain in the hip is due to the surgery and will get OK with time and medicines
