Claritin-D 24 Hour and middle finger

I took the generic version of Claritin-D 24hour 1week ago today for sinus pressure. When I woke up the next morning, after taking the medication my arm started to hurt and an hour later my middle finger on my left hand went numb. I thought ok this will wear off soon, but later that day my entire arm started to go numb and I started having crazy thoughts. I started crying uncontrollably, having thoughts that i was dying, heart rate increased,started sweating. I called my mom crying because I thought I was loosing my mind. I thought i was really dying and i wanted to just so i wouldn't have to deal with what was happening to me. It all happened so fast. The numbness progressed over the next 2days and by Thurs. i was in a deep state of depression and in the ER with numbness in both arms, hands, and legs, also a high blood pressure of 170/112. After several hours in the ER and a few tests that showed nothing, my Blood pressure came down , but the numbness remained. The ER doctor, who i only saw once for 2mins during my entire stay, had no answers for and referred me to a neurologist(whom I waiting to see). The numbness has worn of some but is not completely gone.I will never take this medicine again.
