Please help! My nephew sent me the following text with a summary of his symptoms. His GP has no clue, and he can't get in to a neurologist till January! Advice?

So some are hard to explain and some i dont really notice or remember until something reminds me. Been going on for many years.
The red swollen join thing. Not sure its its joints. May just be tissue around joints, or skin that makes joints feel sore. Tends to be near joints but tendons are near as well.
Leg paralysis. Fall and cant move legs for 20 mins or so. Only happened twice over last 4 years.
Twitching in pointer finger and thumb. This is my most common twitching
Jerking in shoulder/arm area. Almost like my muscles are contracting pulling arm into body
Hands jerk. This happens quite frequently. Almost looks like i am playing piano and wrist is main source of movement although fingers move as well
All fingers twitching. Looks like playing guitar
Pain in Neck are through shoulders. Pain is anything from dull nagging pain to shooting sharp pain. Different meds help the different pain as well
Numb in both hands. Havent be able to feel them since Aug 1st. Pin pricks feel like dull rubbing. This is accompanied by a dull pain as well, however when shooting pain comes down my shoulders it goes onto hand as well
Leg Twitching. This was bad yesterday in my left leg. I never really paid attention to legs before so idk if it happens more or not. I'm in so much pain all the time its hard to notice things sometimes
Numbness in forearms
Numbness in neck (noticed the other night but think has been that way for a while).
Trouble sleeping, even when pain is tolerable
Think this is a good start. I told wife we need to write stuff down as I feel it or it happens. Who knows how much stuff has happened over the years and i ignored
