Hi. Thanks for your query. Noted the history of sick spells, dry vomiting, nothing comes out, shaky inside, weakness, dizziness. Tests of blood, CAT scan of brain normal. can not get out of bed, no appetite, strange feeling, wants to know what to do further. I would advise you the following as per the history you have provided: Dry vomiting or retching can be due to gastritis, esophagitis, some problem inside the abdomen causing irritation of the stomach and dry vomiting occurring as a reflex mechanism. Hence Upper GI endoscopy, liver function tests of the blood, urea and creatinine can help in diagnosis, as well as the ultrasonography and CT scan of the abdomen may be needed. Since you are suffering like a clock, get an appropriate treatment round the clock to alleviate the symptoms in the form of PPI, antacid and motility regulator.
