I have been having occasional spikes in blood pressure. recently, I went to the doctor and told her about some of my symptoms and she said I had anxiety. She prescribed Paxil. After 2 days, I had some side effects so I stopped taking it. Tonight I feel sleep on the couch,. My husband woke me up to go to bed and after I got up I felt faint. I didn t pass out but I haven t felt that way before. Should I be concerned?
