Weird Cravings/Strange Symptoms

[Ally20]

Hi. I'm not sure if I'm posting this in the right place or if this is anything at all.

I recently started getting these insane cravings for meats. I have never been a vegetarian and have always enjoyed eating meat but this is different. It's like I HAVE to have meat when I'm eating to the point that I don't even want cereal for breakfast, I'll just eat cold cuts. I'm eating carbs still because I'll make pasta and sandwiches but they will be loaded with meat.

Also around the same time, my cramps when I get my period have become debiliattingly painful. I'm 21 years old but my last three I have turned pale, broken out in a sweat, and could hardly breath from the pain. I cramp up but this started happening around the meat cravings.

The last thing that I've noticed that started around the same time is that when I sit with my legs under me for even 5 minuets or I can't immediately move them because they hurt so bad. I have to keep them bent up and slowly extend them. It feels like there isn't any blood in them after words because I can feel it rushing to my toes. I know how that sounds dumb, like obviously blood is going to need to circulate back to your legs after you've been sitting on them but there's this new incredibly painful/stiff feeling in them.

I'm not even sure if this is anything. The only reason that makes me suspicious is that they happened around the same time. Well that and the meat cravings. They are seriously unreal. I wasn't sure if this could be some type of protein/iron deficiency. My roommate thought it could be anemia but were definitely not med students.

Anyone have any ideas?
