MSF 27 MS and Trigeminal neuralgia (TN)
I hope this helps.
What Causes Trigeminal Neuralgia?
The pain associated with trigeminal neuralgia represents an irritation of the nerve. The cause of the pain usually is due to contact between a healthy artery or vein and the trigeminal nerve at the base of the brain. This places pressure on the nerve as it enters the brain and causes the nerve to misfire.
Other causes of trigeminal neuralgia include pressure of a tumor on the nerve or multiple sclerosis, which damages the myelin sheaths that insulate and help conduct electrical impulses across nerve cells. Development of trigeminal neuralgia in a young adult suggests the possibility of multiple sclerosis.
Secondary Symptomatic Trigeminal Neuralgia (STN): Pain resulting from multiple sclerosis.
The pain is often described as an excruciating sensation, similar to an electric shock. The attacks can be so severe that you are unable to do anything during them, and the pain can sometimes bring you to your knees.
Trigeminal neuralgia usually only affects one side of your face. In rare cases it can affect both sides, although not at the same time. The pain can be in the teeth, the lower jaw, upper jaw, cheek and, less commonly, in the forehead or the eye.
You may feel aware of an impending attack of pain, though these usually come unexpectedly.
After the main, severe pain has subsided, you may experience a slight ache or burning feeling. There may also be a constant throbbing, aching or burning sensation between attacks.
You may have episodes of pain lasting regularly for days, weeks or months at a time. It is possible for the pain to then disappear completely and not recur for several months or years (a period known as “remission”). However, in severe cases, attacks may occur hundreds of times a day, and there may be no periods of remission.
Symptom triggers
Attacks of trigeminal neuralgia can be triggered by certain actions or movements, such as:
• talking
• smiling
• chewing
• brushing your teeth
• washing your face
• a light touch
• shaving or putting on make-up
• swallowing
• kissing
• a cool breeze or air conditioning
• head movements
• vibrations, such as walking or a car journey
However, pain can occur spontaneously with no triggers whatsoever.

Don't be afraid of it that only makes you worse, think of a solution, don't think about all the logic behind it and don't go to the dr., you gotta love yourself enough to find a homeopathic solution...

Yes, retro bulbar neuritis or optic neuritis was what I was diagnosed with in the process of finding that I had MS. It felt like I pulled an eye muscle, I could look hard left, right up or down then the light sensitivity can get so bad I have to where sunglasses AT NIGHT because the street and traffic lights are too bright for me.

Your challenge is potentially Trigeminal neuralgia. There's an article on the subject you might find helpful: https://multiplesclerosisnewstoday.com/2017/07/...

In 1990 they said the nerves in my left eye was pretty much gone. And I was told don't go back up on roofs and stay out of the heat. I was getting staying pains behind my eyes very intense pain for 30 to 40 seconds. Then it will slowly go away
