I Can Feel My Heart Beating In My Throat

It hasn t gone away and it started about 5 minutes ago. I have had anxiety-related palpitations before, but my heart beat is steady right now, it just goes funny on and off. Two days ago I started taking Epilim and Isoptin SR, could this have anything to do with it? I am female, 15 years old. Thanks No, I know what I m talking about. I feel it beating in my chest and it flutters sometimes. It hasn t gone away for a while now. Also, I am taking those medications for supposed migraine related constant numbness and visual disturbances. It feels like constant palpitations. I have symptoms of numbness over a number of places on my body (both sides), and small dots that come and go constantly in my vision. (They are not something in my eye, they are coming from inside my brain) The neurologist says it is probably migraine, and gave me those meds. I m probably stressed because I have been through a lot of crap this year and I just met my long lost sister I ve never met before.
