yeah Im guessing your Seriously Dehydrated, which is a major cause of constipation and also a cause of tight muscles like your describing! Take some Senakot S its a stool softener and works well!
I also had my wife pick me up Dulcolax cause i wanted to try a different brand of Stool softener, well she accidently bought the Dulcolax LAXATIVE, instead of the softener, and i took 5 of those fucker without realizing they were straight laxative, and i can honestly tell you I was shitting so bad that I was praying and talking to GOD while sitting on the toilet lmao! If you wanna shit bro grab the Dulcolax Laxative, it hurt my belly so fucking bad it woke me from my sleep at 3am and i ran to the toilet and sat there Praying to the Lord to make the pooping and cramps in my belly stop! I sat there so long both legs went numb lol,
Crazy i know, and prolly way too much info i shared, but i promise ya if ya need to go, grab the Dulcalax Laxative, or the stool softener from Senakot s
