Just seems to be getting worse. In the morning I'm fine and throughout the day my neck starts to hurt and swell on the left side and I feel mega dizzy. I was feeling the back of my neck today and it was quite flat, if I told anyone to feel it they won't notice a thing now the muscle is bulging right out and I'm dizzy. I think I will go to the hospital tomorrow but it's hard seeing as I'm not dizzy and my neck muscle doesn't stick out in the day.
