I Am Experiencing A Severe Bout Of Pain And Was

I am experiencing a severe bout of pain and was just refreshing my memory on bentyl. I was prescribed over 6 years ago with my first bout of diverticulitis. Since then I take 5 hydrocodone per day, gabapentin, nortriptlin, lexapro, beryl as needed up to 4 per day. I read that one person takes up to 8 per day. The only thing that ever really helps is laying flat with heat pad. I am so tired of all this pain. I have seen countless docs and no one seems to have an answer other than IBD. I'm assuming after 2 days of diarrhea my gut just needs to rest.
Thanks for any input.
