I am on day 14 of 10mg of paxil. I have slowly been getting better as I have been diagnosed with GAD. My feelings of chest pressure and tingling have mostly gone away and I can eat most of the times.Today I am getting like a burning sensation down on the back of my arms and upper back. I also got really irritable. Today. I still have the racing thoughts about my condition. Does anyone know when this medicine will work. Can these be side effects that will go away.
