I have been experiencing abdominal pain that seems to come in waves and woke me up from sleep last night. I am not vomiting and do not have abnormal bowel movements they are regular, normal, light, not runny and but smaller than usual. The pain is on both sides and feels sharp and uncomfortable, my stomach rumbles and then the pain goes away. Seems to be worse when I eat or drink... no fever, or chills and I have never had this before.
