I seem to have a recurrent pain on the left side right where the bottom of my abdomen meets the inner very top of my thigh. right at that junction. Worse when I move

I dont do sports and dont have a hernia but do have a varioclele in my testicle and long standing left sided abdominal pain which has defied diagnosis despite endeless tests

Is there any point in bandaging / taping if so how or wearing a brace if so which one

Thanks
