Whatever drugs you are on the pain and numbness can overwhelm their effect and cause an attack, I'm afraid. With the doses of the meds I'm on I shouldn't feel anything ever, but the numbness is a nagging irritant, and going out in a breeze under about 45℉ or having to take my heart GTN spray guarantees the pain to sear through my face.
As to your next post, never put yourself down for asking questions, it is how you learn the truth from fellow sufferers.
Always make the most of your good periods and avoid triggers, bad days will come and go.
