This happens to me all the time this time of year.It is a coincidence I happen to be on here tonight reading this - I've been away for nearly two years. I get the EXACT FEELING yo describe often this time of year. You can check my posts from YEARS ago worried about nearly the same thing. Really worrisome stuff the first few times you go through it.What I found was I get sinus infections in the winter time. In my case, they don't produce a stuffy nose like I think of when I get sinus infections because of a deviated septum and blockages above my nasal chamber. So instead, the stuff just clogs my head, and drips down the back of my throat at night, causing mild inflammation there. Those mild differences in head congestion and throat inflammation cause subtle changes - I strain a bit more when speaking (often I don't notice it), I work my neck muscles differently even to hold my head up, and I'm not as quick with thought, speech etc. Very MILD mind you, so that consciously you aren't even noticing these things. Also, I tend to find that this is the time of year when my tongue twitches flare too. Usually in tandem with the neck spasms and some mild pain on the back half of my tongue (never in front - who knows why). Again, had it for years, and nothing's come of it.All of this produces that weird - "I can't talk right, and my neck twitches all the time feeling". Tongue twitches and in my case intermittent back of head and neck soreness/stiffness. Everything you describe to a T. In the end, I found that an antibiotic (non-floroquinolone) for three weeks made me feel a hell of a lot better and cleared up these issues too for the most part.If you search the archives for this time of year, as I did long ago, you will find it jammed with these tongue, neck, speech issues. From January through April - in other words, from sinus infection season straight through allergy season. Like clockwork. And I firml;y believe what is happening is the infection/allergic reaction is causing moderate changes to the sinus cavities and throat (in the form of inflammation and mild soreness) and that triggers a whole slew of subtle reactions that result in your dilemma. I'd start even with some Vitamin C & D to help support the immune system, and a POSSIBLE trip to the doc to check into an antibiotic if you feel a sinus infection could be an issue, and relax/rest. I think this usually passes in 3-5 days after you break free of the grip of having your mind fixed on it and worry.Don't forget, even when we feel a sinus infection has "passed" on its own, it rarely fully resolves without antibiotic treatment (if it is bacterial of course), so even an infection weeks ago could still be producing your symptoms. I hope this helps. Don't worry - I had/have exactly what yo describe and nearly five years later, I'm better than ever!Take care - pug
