I have been dealing with frequent constipation over the past two weeks accompanied by lots of itching but i don't have any rashes. what could it be?

Likely unrelated: Of course, this time of year the biggest problem with itchy skin is dryness due to being inside with heated air. Generous moisturization is needed. Perhaps the constipation IS related: being cooped up inside is contributing to inactivity. Keep working on constipation with lots of water/hydration, increased fiber in diet, & daily exercise, especially walking. Good wishes:)
