25 and everything hurts.

lo

So here I am lately been feeling so bad. My whole body has aches and pains somewhere but it's always something ughh my knees, my back the heels of my feet, my ankles. I'm always tired my period isn't until a week from now but my tummy cramps and back cramps are ridiculous!! Is it because I'm getting older? Is my food choices finally catching up to me? Should I see a doctor about this? Like idk if it's something serious or this just happens. Someone please help lol give me advice please.
