As you said, it could be a torn/ pulled /strained muscle. Home treatment includes applying ice for 20 minutes and taking ibuprofen for the pain. Try not to use the muscle so no situps or abdominal exercises for a while. Stretching or reaching over your head may also pull on the muscle.
If it worsens or a fever or other symptom develops you should see a doctor.

I am suffering from serve lower stomach and rectal pain.
Sometimes it is so sever it feels like spams or some one
is tying me into knots. Have had almost every kind of test on the market and all are negative, but the pain does not go away. Personaly I am no longer interested
in medication which in most cases is not helping anyway.
ANY HELP WILL BE GREATLY APPRECIATED

I was thinking it could possibly be a hernia but I've never heard of a hernia causing rectal pain. It sounds like severe menstrual cramps also. Does this occur during menstruation or right before your period comes on?

No this has nothing to do with menstrual cramps, as I am over 70. This has been going on for over a year, and
doctors still do not know what it is, so you can see why
I am at my wits need. Again if anyone has any ideas your imput would be greatly appreciated.

Sorry darleneb. I'm at a loss. Let's hope someone else can answer your question. Good luck.
