You don't take ALL of the medications at the same time do you? Some are in the same class of drugs. I can't imagine any one doctor would prescribe them at the same time like that. I mean, I don't know for sure and in psychiatry they do come up with cocktails. But seroquel and latuda stand out. Perhaps you take some to counter issues with others like benztropine to counter tardive dyskinesia . Lithiam is great for intrusive thoughts but not used much otherwise and on top of two other antipsychotics. Seems a lot. Anyway, tell us more. Are your psychiatric symptoms under control? Is your blood pressure/heart situation also stable? And when you say pain, can you describe it in more detail?
This is a lot of medicine, I hope you find some relief. Have you considered your diet as a possible cause, food intolerances can cause all sorts of symptoms not just gastrointestinal problems. Personally, I cut out wheat and gluten because I had gas and surprise, my gastrointestinal problems got better, anxiety went away ,, pain went away. Sometimes intolerance cause leaky gut, then vitamin deficiency, then hormonal imbalance. Everything is related. If not wheat and gluten, possibly other common allergens like eggs, dairy, or sometimes carbs for some people. My lifelong anxiety went away in 10 days on gluten free diet. I had a stutter my whole life, now I feel better. I don’t know if this might help you but it’s worth a try, maybe .
