@Mike34 It is interesting you talk about water sensations. I've had a lot of sensations which seem to be similar to nerve or microvascular dynsfunction. I've had these cold wet water sensations for over 10 year now.
Ten years ago I just had a neck stiffness and felt like cold wet water was running down my legs. It was only a few years later I had a sudden attack of dizziness, intense face and ear pain, jaw pain and tinnitus.
I've also had flair ups after upper respiratory infections for a number of years that would cause rain drop sensations for a few weeks all over that would turn into stinging sensations that would last for months. That went on for years until it seems to have finally stopped. It was triggered by trying to take antibiotics and other supplements to kill a possible Borrelia and Bartonella infection that might be causing the muscle pains.
I've been talking with @MrCartman here for a number of years and he seems to have some similar stuff, but no wet water sensations like I get. I get it mostly in my legs crossing them or putting pressure.
My tinnitus is on the right side mostly and the pain is mostly my right jaw side and neck side, though I have myofascial pain syndrome and trigger points in many places on my body. I also get a weird slight numbness below my eyes and also get dry eye syndrome.
I've noticed recently that there seems to be two large bone like bumps on the right upper side of my neck toward the back. It may be the bones are twisted and not symmetrical since I don't feel that in the same place on the left side.
I've been searching for a primary care physician for years and recently signed up for a new one at a hospital near me. I'll have a visit in a few months to go over my health issues and I'll mention these bumps and neck pain with more focus on the neck than the jaw.
I've been the whole TMJ thing years ago. It was a lost cause. I've also been doing trigger point therapy for years on the SCM and other muscles without any lasting or major improvement, but it can help reduce some pain when needed.
I thought a Bartonella nano-trap antigen test would be a good idea from Ceres Nanoscience, but they never got the funding to manufacture the test.
Oh, I also get flushing on the neck, and upper torso, which may be related to the problem, though I don't get rosacea on my face, but that can be related to dry eyes, which I do have.
Some say Bartonella is a micro-vascular infection and I think the water sensations could be caused by a microvascular dysfunction. It may be a blood thing more than a nerve thing, or both since some of the sensory nerves are tied to blood supply in the microvascularature I think.
