Dixi,
I feel like you have one nasty case of Health Anxiety. I know your symptoms are real and scary but do try to remember that if your anxiety is high your symptoms may get blown out of proportion. Remember your symptoms are not necessarily reflective of a serious medical condition.
I really feel you need to make your appointment with your physician and talk to him/her about how bad you are feeling as it does appear that your anxiety is ruling your life right now.
If you have medication for your anxiety I hope you are using it.
Gentle Hugs
Kitt
