My stomach has been extremely itchy for about a month. also my breasts and nipples have been sore for a week not pregnant, not ready for period, no dry skin, no issues in past.

You : You may be dealing with an allergic reaction. Are you using a new soap, lotion or detergent? You can try over the counter benadryl (diphenhydramine). Based on the date of this post, if your symptoms are still present you should be evaluated by your primary care provider. Good luck.

Breast pain ?'s : At age 46, your ovaries are being stimulated much more than in one's 20's and 30's, as it takes more stimulation to produce ovulation. The estrogen levels being much higher will in turn stimulate the breasts and nipple areas and cause pain/sensitivity. This may not be related to your "itchy" stomach. Ask your gyn physician about low dose oral bcps which will stop ovarian estrogen production.
