It's better to see your primary care. Just give them a call ask for a nurse.

I don't know your medical history or the details like where exactly in the lower abdomen. I would also put pressure to go into detail

Dizziness can be caused by a lot of different things, like anxiety to constipation and gas. Forceful defecation can also cause more Dizziness since your heart shunts your blood towards your lower abdomen decreasing oxygen to the brain and heart hence being pale. Gagging can be caused by the severe pain.

I don't know your age your family history I think those questions may be asked when you visit the clinic would be helpful to know
