Hi,I have had a sharp cramp pain in my left side for three Weeks. It had increasingly gotten worse and wakes me up out of my sleep. I cant stand longer than 45 mins.I have been tested for and told it is not kidney stones, anything urinary, or a heart problem. I constantly feel drunk and have become somewhat absent minded.
From available facts, u may be having ulcer or gastritis or simply a spasm in muscle. These are not diagnosed in routine ultrasonography. Please clarify your Chat Doctor.  Please also tell if u feel breathless or have night sweats or fever. Do u have to sit in bed to breath.
