Serious headache and body pains

6 weeks 2 days. And I've been having a very severe headache and my body aches all over. Anyone else dealing with this? Or have any tips on how to make it stop? The doctor said the headache is caused by one of my back muscles spasming. They gave me a low dose of flexerol (spelling) that isn't doing anything for me at all. Not even Tylenol is helping. I'm absolutely miserable. And did I mention I have a toddler that refuses to listen to a thing I say and has been screaming since he woke up?
