Pain

Im a 37 female suffered with constipation most of my life this year it's been on and off going a few days with no Bms and then a few very large hard to get out bms , followed by days of intense cramping (no bms) in my left side that comes and goes in waves and finally leaves once iv managed to go . Iv woken up today with the same pains but 100 times worse , sitting up hurts , walking around hurts and the left side of my abdomen is cramping something awful , this is after days of having atleast 1 poop a day.

Im on pain meds and my fourth lot of antibiotics in 4 months for a separate issue maybe this has something to do with the pain level change . Any ideas
