My arms ans shoulders feel tense and my throat feels tight....weird... I wonder what the problem is.
Those are typical signs of anxiety. The throat tightening can be the initial sign of a panic attack.
Consider what is going on and if anything in particular is making you apprehensive. Breathe slow. Count numbers. But get calm and see if it helps. If you feel worse and your heart starts racing, you feel fear without a logical reason, that can be a panic attack.
If nothing is making you anxious, then, I don't know what's going on.
My throat gets to where I cannot swallow pills etc. and my rheumy said that the esophagus can swell in a flare. The tightness is past the breathing tube. I use gummy bears to push pills on down as they get stuck a lot. Always have something to drink close by when eating or taking meds as I learned the hard way.
Take care,
