Yesterday afternoon I started to have mild chest pains, headache, numbness in my arms/legs, dizziness, and begain to sweat profusely. All of this came on as I was laying on the couch watching tv. I decided that I may feel better if I took a cool shower, and after about 15 minutes the symptoms began to go away. Last night I had alot of difficulty sleeping and the chest pain seemed to worsen and spread to the upper left side of my back. I was finally able to get to sleep and when I woke up this morning I felt fine however my bed was completely soaked from sweat dispite having my a/c set at 68. I got up and started my day as normal. At about 9:30 the headache as well as the numbness/tingling started to come back. I started to get very dizzy and thought maybe some fresh air would help so I went outside and sat down. All of my symptoms started to get worse and the chest pain came back and was pretty severe. I began to start pouring sweat and feeling disorientated. At this point I stumbled my way back inside and told my friend to take me to the hospital. On the ride there my condition continued to worsen. I begain to loose basic motor skills and functions, and lost my ability to speak. Also, in addition to my arms and legs, I had severe numbness in my mouth/tongue as well as my stomach. I also began to have a fuzzy vibrating feeling......it felt as if someone was shaking my whole body. When we arrived at the hospital I was unable to walk on my own and had to basically get carried in by my friend. When I was being asked questions, it was like I knew how to respond....and I tried so hard to ..but I was still unable to speak....the words were coming out jibberish no matter how hard I tried. At this point both my hands and arms locked up and contorted. After about 15 or 20 minutes I started to regain my speech and motor skills and after about 2 or 3 hours all the symptoms were gone and I felt perfectly fine. Blood & urine tests, CT scan, chest xray & mri all showed nothing abnormal. They did not do an ekg...I dont know if I should have had one but, I didn't get one. About 4 hours later they sent me on my way and said it was a "vagal reaction" and nothing to worry about. Based on the paperwork they gave me explaining vagal reaction, it does not seem like it is correct. Also, by the time I got home, the dizziness, sweating, mild numbness, mild chest pain , and headache had all returned. Also, I don't know if it has anything to do with this but about 2 months ago I experienced sudden complete loss of vision in my eye. They never figured out the cause, and my vision returned 2 days later. I am a 28 year old male, in great physical shape, eat a healthy balanced diet (which i have made no recent changes to), I don't do drugs, and I am not perscribed any medications. Please let me know if you have any ideas. Thank you all in advance for your help!
