Question

Hi, I have an ache that seems to come and go. It is in the left hand side of my body beytween hip and bottom of ribcage. It does move about sometimes creeping nearer my back but at the same height and sometimes nearer my front and pelvis. I might describe it sometimes as a tickly ache. I don't notice any other symptoms, apart from a general feeling of not being quite 100%, and maybe some bloating. I have been checked out by a Gastro expert twice earlier this year who couldn't find anything, and have recently had a full health check and they didn't find anytihng either. They put it down to stresses and strains. I do suffer from some food allergies, and am going to get some allergy testing done. I am also wondering if it might be muscular, its worse when I am sat down. I have revised seating position (desk job), and now loosen trousers whilst sat down. Any help appreciated.
