<human>: Woke up this morning with my my right thumb, and 2 fingers next to the thumb completely numb and (tingling, pins and needles sensation).  Called my PCP but office is closed due to weather.  Should I go to ER?  I have been having extreme cramping pain in my lower abdomen for the last 4 days with BMs about every 2-3 hours over the past 36 hours.  I have had stomach problems for over a year now and doctors can not find out why.  I have had every test in the book.  Something is keeping me from digesting food properly, I just belch it right back up 15-20 minutes after eating.  I go 4-5 days without a BM and then all of a sudden, bam, I will have 6-8 BMs in one day.  Something is not right with the stomach.  I have seen 2 different gastro. with no luck.  The abdomen pain is killing me, very painful the last 4 days.  Please reply.  I am a 62 year old male in fair health and live in Chattanooga, TN.  Thank you.
<bot>: Hi. Thanks for your query. The classical symptoms of alternating loose motions and constipation along with other symptoms is more suggestive of :Cancer of the intestinal tract. I would advise you the following tests:Investigations:*Routine blood investigations like Complete blood picture, blood sugar, urea, creatinine, liver function tests, thyroid function tests.*Urine -routine and microscopy*Stool: routine, microscopy, occult blood, culture and sensitivity.*Ultrasonography of abdomen, *Colonoscopy All these investigations should be within normal limits for one to say you have Insight colonoscopy shows cancer, get a biopsy, CT scan of the abdomen and proceed further. Treatment:Get a course of an antibiotic, metronidazole, probiotic and see the results, it is possible that you may get a relief. If not, go for further tests.
