Hi I am going to see my doctor Thursday. I used to suffer from panic attacks I took Paxil 5mg qd. I thought this was related to my divorce at the time so I stopped taking them about 12 years ago. I have noticed now I am very fatigued, my heart feels like it pounds sometimes, my hands go numb they are numb right now, I seem to have back pain only across the top of my back. I have difficulty concentrating and focusing. My stress level is the same about moderate. I was given a muscle relaxer I took one pill and did not take anymore as I felt it was making my heart pound more.
