Anna, did you ever go to Fibro 101 and check out the link called Symptoms? All that you are describing are symptoms of fibro.
You just need a doctor that knows about fibro. No, feeling like this isn't normal for the average person but it can be "normal" for people with fibromyalgia. I have back, shoulder, ankle, and hip pains, vision problems that come and go, hot and cold issues, feelings like bugs or water are running down my leg, buzzing, heart palpitations...I could go on further but this is how fibro hits me. Now, everyone is different. We don't have ALL of the symptoms but we usually have quite a few.
Once you get the help you need, you will see that you can have a full and enjoyable life in spite of fibro. I know I sure have. Just arm yourself with knowledge of this illness and that not only helps you but also helps you be your own advocate with this illness. You won't feel like you are going crazy, either. So, please read Fibro 101. I put that together and send everyone to that thread when they first come on the forum because it's packed with good information.
