In the early 80's I was told my random weird sensations on one side of my body was Shingles, despite there never being a rash.
I was told I had MS in the late 80s when I went blind in one eye for a few months. The neuro didn't want to put me through a lumbar puncture as my symptoms hadn't been too bad. I was told to go home and live my life until it got worse.
I returned to the GP in the early 2000s with more symptoms and was told I was depressed and put on antidepressants. I carried on visiting the GP, getting worse and worse and was told I had Fibromyalgia in 2009.
One doctor has written "difficult patient" in my notes as I kept going back for help.
I self-referred to the local hospital physio in 2017 after having difficulties with one leg. The physio immediately suggested MS so I told her I'd already been diagnosed. She sent me on to another neurologist straight away where I was tested for a B12 deficiency. My levels were higher than normal range.
A year later I finally had a lumbar puncture and a diagnosis of MS. I was then told it was too late for the medications they normally give for RRMS.
Definitely push for MRI and OCT if you've had any eye issues such as faded colours (mine comes and goes). A visual evoked potential test can also be given.
I had clonus for decades but it disappeared a decade ago. Keep pushing for tests, but a really simple one to do yourself is the Babinski plantar reflex test. I've been positive for this since I was a kid and thought it normal (older brothers who'd hold me down and "tickle" me), as my brothers had the negative response.
Good luck to everyone looking for answers.
