Need advice.

For the last two weeks my boobs been having this "lighting bolt" cramp on both side (but i checked if any lumps and there are none), and my nipples are supper sensitive my parent cant even touch them.

The other thing is, the lower part of my belly has been cramping but doesnt feel like period cramps either, their like "lighting blots" to like a "tugging" feeling, and my lower back has been so sore the last 2 weeks aswell.

I went into the doctors and they said my thyroid is elevated and i changed my dite for about a week now but those pains didnt change they still come and go.

What can this mean?
