I am in a similar, but perhaps smaller boat. I am in pain in the evenings, most days. But, my daytimes are usually OK. (tolerable for the most part) My nights, I moan and groan as food tries to desperately digest and make it through my body. Painful process, and to be quite frank I am OVER IT! So tired of feeling ****** (no pun intended) I rarely take pain meeds, as they only seem to constipate. I use a hot water bottle/heating pad and I am researching the medicinal marijuana route. I don't see the doc until Sept 12th.
YOU my friend, NEED to see a doc. Where do you live? I know that here in Canada, there's always a way to see a doc, but understand many countries do not have that luxury. I completely feel your pain, and REALLY hope you can get into see someone. Who do you normally follow up with? GP or GI doc? Good luck! Keep me posted!
