Pain

I'm not sure why, but it's been a few months my head is in pain most of the times. I'm not sure if its like migraine or anything. But I hope not. The thing is I can't focus on my drwaings, because i have to concentrate when doing them. Time right now is very crucial. Yet, I haven't completed my exterior perspective. I've just drawn the base.. Hmm.. Please, let the pain just go away... Poof!!
