I started taking Contrave 5 days ago. On day 4 & 5 I noticed i have been having extremely wicked headaches and pressure at the back of my head. When i bend down, the pressure and pain at the back of my head feels like it is moving to the front of my head and is a constant throbbing type headache. It feels like a terrible sinus headache. Has anyone else felt this in the beginning days of taking Contrave? I don't know if I should continue taking this medication, but my Dr. prescribed it so I could lose weight.
