Although some members of this forum have disagreed with me on this previously, i believe this type of symptom is technically classified as Peripheral Neuropathy.
It was a major symptom of the relapse that prompted my joining the âMS clubâ. And it remains as a symptom, but to a much lesser degree today, several years later.
The sensation of water trickling over the skin, or more specifically for me, a gang of ants having a rave dance party were common but not constant.
The effect on my strong hand (aka the one i write with etc) was challenging; simple dexterity was tricky; forming a fist was never guaranteed nor was any movement without visual confirmation; putting a glove on for example was an effort of trial and error; with two or more (!) fingers going into one finger hole in the glove, even though it all felt okay.
I would practise doing âthe spock signâ. in the early days, efforts to spread fingers apart one at a time, would see my fingers flex downwards instead.
I found this for you:
What are the symptoms of peripheral nerve damage?
Sensory nerve damage causes a variety of symptoms because sensory nerves have a broad range of functions. Larger sensory fibers enclosed in myelin register vibration, light touch, and position sense. Damage to large sensory fibers impairs touch, resulting in a general decrease in sensation. Since this is felt most in the hands and feet, people may feel as if they are wearing gloves and stockings even when they are not. This damage to larger sensory fibers may contribute to the loss of reflexes. Loss of position sense often makes people unable to coordinate complex movements like walking or fastening buttons, or to maintain their balance when their eyes are shut.

Personally, i would be disinclined to throw drugs at this until it became a significant, negative impact on your life. I would instead exercise the affected areas to best appreciate your limitations, experiment with adaptation (my hand writing and typing skills needed a fine tune to accommodate) and find a measure by which to gauge your improvement WHICH WILL HAPPEN!
The very best of luck.
