Good morning what cause a itchy feeling on the inside of tummy even strong enough to wake me?

Researchers postulate that the intestines have receptors like our skin has and can produce itchy sensations. These may be related to irritable bowel syndrome. Do you have episodes of cramping,bloating & diarrhea which may be triggered by certain foods or stress? If so your itchy abdomen may be a variant or part of irritable bowel syndrome. You could consult a gastroenterologist for advice.
