Spasm - it hits me when it shouldn't

It visited me as if it's my beloved during Valentine's. Again now, when I have a super major project in hand and my marriage just a few months away, it hits me again! And this time my spasm has come with a companion, another killer pain in the lower back. God, I hate bed rests. I know it's a punishment for long working hours, but then sometimes they are unavoidable, aren't they?
