I'm 3 days post-migraine. Sunday was the worst one I've had in years and years. Aura on left, extreme pain on the right, nausea, sensitivity to noise, blah, blah, blah. Today, I have a dull ache on the right hand base of my skull, overall fatigue on my right shoulder and arm as well. Otherwise, I'm feeling ok (apart from GI upset this morning related to celiac). I'm not sure if this is related to painkiller withdrawal or what??
