I spent a day stripping wallpaper from a ceiling recently which really flared up my burning symptoms in the right side of my neck (sternocleidomastoid and scalenes) so I've been looking into trigger point therapy and discovered what I think are a few knots in right side of my neck though I'm not sure if they are just lymph nodes due to their position so I just wanted to check to make sure before I start deep massaging them and possibly damaging a node or something.
Here's a photo of where the biggest 'knot' (my finger is directly on it). It's about halfway down the side of my neck, but closer to the back than the front. It feels like the size of a small pea and there feels like a couple of smaller knots just below it. I also seem to have a smaller knot directly on the opposite side of the neck. These have been the only bumps I've found.
