Severe pain

Hi!

This morning I woke up and was a bit sore in my lower abdomen, I sneezed as I got allergies and I felt a faint but sharp pain also in the lower abdomen.

Later during the day the pain I my lower abdomen got more severe and I couldn't stand up straight without the pain being worse.

Is this ligament pains? I have called my doctor but the are so busy so the will call me in a couple of hours.

I've tried taking some pain relief but no effect there. The pain is not just on one side, it's from side to side.

If it is ligament pains, what can I do? This pain is like period pains but times 10,000
