I messed up today

I deep cleaned my apartment today. I feel cleaned every single thing in every single room because today was a day had energy and didn’t feel sick (I’m 10+6). I cleaned for 7 hours straight. No breaks. I think I messed up bad... I am cramping and my back hurts so bad, like my butt bone area. I cannot stand up or walk without help. Even laying down hurts so bad. Coughing/sneezing/laughing - everything makes my backache worse. Has anyone had this happen to them?
