Hello,
Thank you for your query at DoctorSpring.com
I have reviewed your entire history, and such recurrent abdominal pain could be due to Proctalgia Fugax.
It occurs due to spasm of the pelvic floor muscle. The cause is still not well established.
The other causes include proctitis, anal fissure and solitary rectal ulcer syndrome.
Regarding the headache, it could be secondary to all the stress you have been having. Do you repeatedly clench your jaw? Even that can lead to headache associated with pain around the jaw. What about your blood pressure?
Feel free to discuss further,
Regards.
