For over a month, I have had prolonged stomach problems. My symptoms started with severe nausea, vomiting, headache, watery stools, unable to keep any food down, and extreme fatigue. This was consistent for over 2 weeks. I went to the doctor, he tested me for parasites and other things. Then said I probally have a viral infection. It should clear up and prescribed Cipro 500mg. Well with the severe nausea I couldn't keep the medication down. Along with that medication, I was on Prednisone 10mg, Protronix 40mg, Atenolol 25mg, naproxen 500mg, Planiquil 200mg and Quinacrine 100mg daily. I stopped taking all medication except the prednisone and the protronix. I started feeling a little better after that, but I have still been extremely fatigued, have little appitite and have been experiencing weight loss. My primary doctor referred me to a gastro doctor, but said that I could have an ulcer. I have been reading up on stomach cancer and I have a lot of those symptoms as well. What test should my gastro doctor have me taking and how long should I just sit and wait.
