Hi. Thanks for your query. Read and understood your problems. Cramps - pain - hot flashes - numbness of both legs when you lie down - and low back ache - crusts on nipples... All these symptoms taken together can be due to intestinal infection or intestinal obstruction causing all the other associated symptoms. I would suggest you the following: Clinical evaluation and actual physical examination by a General Surgeon or a Gastroenterologist. Enteroclysis- meaning barium studies under direct fluroscopy control. CT scan of the abdomen. Routine tests of the blood, urine and stool. The final reports will give an idea and if obstruction you may need Diagnostic Laparoscopy and procedures as needed. If a Medical problem like Tuberculosis or Typhoid. You will also need additional investigations for other symptoms like leg pains and treatment.
