Severe migrane headache from 4 days. A possible withdrawl symptom?

Hello,

I finished 14 days of no PMO and this is the longest ever. I could see some benefits util a severe migraine headache(like never before) hit me on day 11 and it's still persistent on day 14. Can no PMO be a cause? This was an abrupt stop since I used to masturbate atleast once a day from several years(tried quitting countless times before) and this sudden abrupt stop might have affected dopamine levels in the brain causing this pain. A valid theory?
