I have severe attacks in the sternum area. The pain starts there, (I am always in pain), then it gets worse and goes to both sides and back. It s worse than labor pains! I have had bad constipation also. I have been to ER twice, followed up with my Dr. My blood work came back pristine , that s what the ER Dr. said. My Monocyte level was 51, higher than it should be. My Dr. Wasn t concerned because my WBC was not high. My Dr. prescribed an antacid, 2 times a day, and Myralax. Even with that I do not have a big enough bowel movement. I do not have insurance, so I feel that I am not taken seriously. I have attacks once a month, they last about an hour. The pain is constant tho.
