I've had this for about 5 years now, back when I had a car accident or possibly from a horse riding accident. Here are my symptoms.
I can't walk for more than 10 to 20 minutes without feeling like I'm going to pass out. I get very lightheaded and have to stop and lean against a shelf when I'm in a store. Can't go to movies because it sets off light headedness real bad. Sometimes the spells will be real bad and I'll have tremors afterwards, usually in my arms and a few times all over. After the dizzy spells my stomach will cramp up real bad and I'll get real sleepy afterwards and have to lay down and take a nap. Usually when I have the dizzy spells my heart will start racing and sometimes it's sets off panic attacks. The dizzy spells will also cause pressure behind my eyes and cause major headaches and pain around my ears. When I wake up in the morning I'll feel fine, but once I stand up and move around my heart starts racing and I start to get dizzy. Usually I take some sort of pain medicine and it helps settle them but it usually comes back by the middle of the day. Walking it makes my legs feel weak, my hands and feet will start sweating.
The other day I was at school and I had fallen asleep during class, it wasn't even really asleep, it was more of a shutting my eyes and I as I did so it felt like someone punched me. I jerked forward and as I did that my heart started racing and the dizzy spells got bad and my hands and feet went numb. Then I got real hot afterwards.
I've been through every test, they ruled out ears (vertigo), they ruled out any sort of brain cancer (I do have a cyst in my brain), they said there was nothing wrong with my spine. Could this possibly be POTS?? I looked it up and it has a lot of the same symptoms I have. My heart will race when I stand up and then when I lay down it'll start skipping beats rapidly till it falls into a normal rythm.
Can someone please help me out???
