Had an bad electrocution injury about 15 weeks ago. I've been having severe head and neck pain for the last 6 weeks. Tried several meds but was given Lyrica three days ago. Headache and neck pain is so bad now I wish my head would fall off. I an having some swelling in my face and some dark spots under my eyes. I know it takes Lyrica a few days to work and I want to give it a chance to work. Any suggestions?
