hello,
i have been suffering for almost a year from abdominal pains especially on my lower left side with both constipation and diarrhea. two weeks ago i had very strong pain and dizziness. i also have BM twice a day but never feel that i completely emptied. sometimes i get very dark brown /black stool that's thin and sometimes sticky. i am worried it could be melena! i did blood tests and my hemoglobin is 14.5 (i am 28 yrs old male). i also did a check for peptic ulcer and my stomach was clear. doctors said that it is spastic colon. but i feel extreme fatigue and tiredness with pain in my joints. please help, thank you.
