Have you been checked out or LYME disease? Maybe you should.
I ask because some of your symptoms can be explained by it and you said that nothing showed up in blood tests. Interestingly Lyme Disease is NOT diagnosed on the basis of a blood test.
'CYST' on the brain, I wonder if it is a pituitary adenoma. These can cause an itchy feeling all over your body. Do you have low cortisol or high, or is it cyclical? Did they do a spit test? If so, did they send it time sensitive to the lab?
Do you have mood changes? Fatigue? Losing concentration?
Well, Everywhere. In the back of my feet, under my feet, same with back and front of hands and fingers and toes. On the back my legs, front of my legs, chest, stomach, groin, back, shoulders, along the arms. Face, including lips, nose, eyelids, ears. Sometimes in the ear canal, then the ear lobe, my cheeks, my head. One minute it will be in one spot, like the fingers , then the feet, then the face, then switch to the ears, and so on. All over . It's a twitch, a muscle twitch, and also a skin crawling sensation. I'm awake, it's all day, all night. It lasts, maybe 20 seconds, sometimes longer in one spot then changes to another spot. I have stage four kidney disease, but nothing in any blood tests to cause it. I didn't eat anything different, no medication. No numbness. No weakness and no real pain. Sometimes the twitching can be harder.
The first thing to do is to list:
1. Where the tingling takes place (be specific eg right knee, left foot)
2. Note is other areas tingle at the same time
3. How long it lasts
4. Exactly what the discofort is. IS it tingling? Are your feet asleep? Hand asleep?
5. When did the symptoms commence
6. Has anything in your life changed recently? Did you move house? Eat different foods? Taken medication? Taken vitamins or supplements?
The more you have of a history the better any doctor's diagnosis
