Sorry you're not feeling well, Debbie. Sorry about
the 'arm,' too.
I don't think you're being grumpy--just frustrated! Maybe it's the same junk I've had---low grade fever and worn out. It would have gone away sooner if I hadn't pushed myself to get back to normal, but naps and taking it a little easier, along with lots of fluids finally helped. It was stubborn, though, and hung in there several days.
Also, for my sinus/sore throat issues, I had some very spicy food and I gargled with warm water and apple cider vinegar. Had to watch that (meaning spicy food) carefully with gastritis, but all those 'remedies' combined seemed to do the trick.
Feel much better soon!! Rest up and I hope you find something enjoyable to do.
