I am a 40+ year old female. After eating, sometimes immediately... other times within a few minutes, I experience a low to moderate grade pain in my abdomen/stomach. The pan may last a few minues up to several hours. On occassion, the pain is accompanied with either a sensation to defecate or loose stools and a low grade burn in my abdomen. This has been occuring off and on for a few months with increasing occurrence. Are these symptoms of an ulcer or another digestive issue? Thanks.
