My husband has some back pain (left side mainly) and pain in his stomach (left side) at times. He feels so much better when lying down and feels nauseous when walking and standing up. He has gallstones but the gallbladder is not inflamed, The nausea has been going on for 4 to 5 days. Normally he is very active and not a complainer.
Hi, Welcome to Chat Doctor forum.  It appears that he might be having the urinary tract infection, or stone in the ureter, or may be colon infection. Nausea is common with any unbearable pain.  The gall bladder lies on the right side more over in the upper part of the stomach. So there is no relation with the gall bladder.  For this pain I advise you to consult a urologist for diagnosis, and treatment.  I usually prescribe to my patient with such symptoms lifetime, metonymic acid, dicyclomine HY Chat Doctor.  Wishing for a quick and complete recovery. Thank you.
