It hurts like fucking hell.
Your anal sphincter muscle is connected to everything you do in life. Cough, laugh, fuck, sit, sleep, stand, walk. If you tear the muscle there is no way to be at peace.
I'm prone to get internal cuts and tears because of my Crohn's disease, but this is the first time I've ever torn an internal muscle. Had that stupid cold that's been going around the country, it turned into a tonsil infection because my immune system sucks, went to a walk in clinic and they gave me the worlds strongest 10 day anti-biotic, of course it killed my digistive track so I was hitting the can 4-6 times a day for 10 days+ and in the process tore a huge gash in my anal sphincter muscle.
Now I can't do anything except lay at a weird sideways angle in bed with occasional standing all day because I need to not put pressure on the muscle so it can try to heal. Also not eating because #2's tear it back up to pain level 10 for a dozen hours, so my stomach hates me. Been doing this for 2 days now. Can't even use my computer, typing from my phone while sideways in bed.
Anyhow, it's ok to tear a lot of things, but becareful not to tear your anal sphincter because it's the worst thing ever.
