I Had a meth overdose about a yer ago an since had pain in the middle of abdomen down to belly with a pulsating feeling that increases as I do physical activities. I wake up everyday with a feeling of nausea and vomit and when I Bend over rapidly I get a sharp cramp feelin as if something were to rupture. My Dr. Can t seem to figure out what it is but I will bring up the abdominal aneurism. I m only 25 years old wich is why he thinks I m going to heal on my own. Originally they thought it was gastrointestinal problems but had endoscopy done and everything was perfect. My biggest concern is the pulsating in my abdomen that is exactly where my pain is all te way to my back and right side.
