My doctor prescribed me muscle relaxers for my back since I have slight scoliosis and can't even lay flat on my back without the pain being almost unbearable. I'm in my third trimester so it's only going to worsen. I have reserves about taking them and the pharmacist did too but my OB gave me the go ahead As Needed Only. I was wondering if your doctor's have done the same and if so, how or Has it effected your baby in Any way?
