@Miss lavender I suspect is related somehow, but I don't know. One person suggested once it was just neck strain and that caused the water sensations. The weird thing is that they can be just about anywhere. That points to system central or systemic. Like you I've had an MRI of the brain and upper cervical. The neurologist said the scan was not able to detect the problem.
My neck and back pain are not minor, they are a chronic pain above backrgound pain, but certainly not always extreme. I also have TMJ dysfunction and pain in jaw and temple muscles.
I got water sensations in my feet and legs, but it can be other places too. In the past i even felt rain drops all lover like my face and head.
I was doing a lot of military press when the neck pain started. I was also taking allergy shots, which I stopped. That was 2005/6. Symptoms only increased over the years. 2007 is when the water in the legs started.
For a while a lot of people were talking about lyme disease and I went to one of the "specialists" who said I had it and I tried treatment. I later decided it was not proven diagnosis or treatment. It was after taking the antibiotics that I got the neuropathies all over. My feet even went part numb and burning for 4 weeks about. I had the water in the legs two years before that, but it went away. It came back when I got the antibiotics, but all over. I went to an infectious disease doctor years later and had to beg to get the C6 test (they said it was not available) and it was negative along with the WB test.
I don't think I've ever gotten the wet feeling around my eyes or temples, but I have gotten it in my ears when moving my jaw sometimes.
I worry that exercise might cause the nueorpathies to come back worse again like beet stings, but I'm not sure. It happened twice right after an upper respiratory infection.
