I am sorry to hear that.
How long you have these symptoms?
Do you have nausea, vomiting?
Do you have diarrhea or constipation?
What pain killer you took?
Any other medical condition you have?
I woke up this morning at 7:45 with the symptoms and it's now 10:10pm. At first it felt like a muscular problem but has gotten worse through out the day. It's not too bad when I lie down but when I stand up I'm bent over in pain. There is no nausea or vomiting but at times I feel a tiny bit sick like I could throw up, but it passes very quickly.It kind of feels like constipation but bowl movements have been relatively normal.I took panedeine 'for relief from strong pain' I have no other medical conditions.Some information which I feel may help:Yesterday I drove for 8.5 hours with only one stop. So I was sitting down, rather tense I suppose, for that amount of time. I'm not sure if this could be contributing to the pain. I'm pretty sure it's not muscular though.
I agree with you it does seem muscular.
The following possibilities should be considered:
1. Acute cholecystitis ( gall bladder disease)
2. cute pancreatitis
3. Acute appendicitis
4. Pelvic inflammatory disease
Since, your pain is persistent without any improvement, you need clinical evaluation and a CT scan of the abdomen.
Please proceed to the urgent care.
