Hi I'm worried sick about MND/ALS. I've been having trouble with my left hand for about 6 weeks now. It started with numbness in my hand when I was on my phone I'd shake my hand and it would go. I thought it was just being ony phone so much. Then on my phone again holding my phone in my left hand and using my left thumb to scroll my thumb started shaking. I managed to stop it quickly. The numbness went on and off until last week when I was sitting again on my phone and my top left arm started twitching, I could actually see it twitching. This terrified me. Since then I've had an achy pain right where the twitch was. And I've got small tiny twitches in my calves and thighs ( I've had this before). But I've never had a twitch like that in my arm before. I also have a weak tired feeling in my arms and legs and throat ( again I've had this before on and off for about 7 years). I am under a lot of stress but that twitch in my arm changed everything. I have had a sore neck and shoulder for a while but I'm not sure if your neck pain can cause twitching. I also have a very sore and aching face and I can't open my mouth wide but I do have TMD so I think that's what it is. I've been reading stories about MND and people often had twitching and numb fingers. I'm so so scared. I can't sleep because I'm thinking about MND. My doctors aren't seeing anyone and they'll say it's just anxiety as they always do. I sit and cry alot because of it and my arm is sore when I hold my phone. Not to painful but achey. I'm so worried I've been thinking of ending it all as I truly couldn't handle that diagnosis.
