Strange Neck Bump

Hey guys,
Over the past few months I have been experiencing a gradually reducing range of motion in regards to my neck. Today, to my horror, I realized when I press on the right side of my neck, it feels entirely different than the left side does. It feels like some kind of muscular bulge. This the area I always have neck pain and where my migraines start. Has anyone experienced anything like this?

I get a tightened trigger points in my neck and that when my pain is coming from the area. But I would get it checked for sure!

I had reduced range of motion in my neck too. I tried PT, meds, everything I could think of to help. It was getting dangerous to drive because I couldn't move my head enough to turn and see if the lane next to me was clear. I finally went to a chiropractor and he fixed it in two visits. When I have really tight muscles I see my acupuncturist, she releases the tightness right away.
