I was having what seemed to be panic attacks (fast heart rate and shortness of breath) that lasts only around 10 minutes each attack. I went to the ER because I thought it could be my heart but they did blood work and an EKG and everything was normal and after the attack had finished I felt fine. I then went to see a doctor and they prescribed Paroxetine 20mg daily along with a small dose of Lisinopril for blood pressure. After taking the 4th dose of Paroxetine my entire body went numb while I was sleeping and since then my body has been very numb all over even in my teeth. After that I went to the ER for some odd chest pains I was having and they did x-rays and an EKG and all was normal but they recommended that I stop the Paroxetine until I see my doctor. I haven't had any form of medication in two days but my body is sore and numb all over and my muscles have exagerated movements when I try to move them only a small amount. When I try to sleep it feels like they tense up and begin to shake as if from a seizure keeping me awake at night. During the day my body is so sore and weak that it's hard to walk and my joints pop a lot. My vision is also blurred and my back is killing me. Every muscle in my body feels weak. I'm also having cold sweats during work. At first I thought it might be symptoms of a stroke but my memory and mental abilities aren't impaired and this problem is affecting both sides equally all over. I haven't taken any medications of any kind in several days but the symptoms are just as bad and seem to be getting worse. Could this be serotonin toxicity after so few doses and lasting for so long or could it be an allergic reaction? If not then what could this be? I have a doctor's appointment for this tomorrow and I'm hoping it's all temporary. Thank you.
