Hi there, Thanks for your query. Firstly, vomiting of old food indicates that you may be having intermittent bowel obstruction, possibly due to hernia (particularly when a loop herniates into the pelvis and causing obstruction). You should therefore consult your ER so that surgery of hernia can be done AS EARLY AS POSSIBLE, before it causes complete intestinal obstruction and even gangrene of the herniated intestinal loop. Further, you should take anti-anxiety drug, such as, clonazepam or alprazolam on a regular basis for panic attacks. Consult your doctor and apprise him of my opinion. I am certain that he agree with me, order required tests, and- based on the reports- will prescribe suitable treatment as advised.
