I had a stomach ache yesterday after eating too much. In addition to lower left abdominal pain right under belly button area, my skin itched so badly. I went to sleep and in the morning put an ice pack on it and it stopped. I have diarrhea and upper and lower cramps like I usually do but I never felt this itching before and it's starting again as my stomach is irritated again. Just having some chamomile and ginger tea. Has anyone had this itching? There is no visible rash, it just itches where it hurts.
