Received laser treatment for spider veins on my cheeks & nose 4 days ago. The right side of my face is fine, virtually no bruising or redness, but the left side is bruised and swollen. The muscles on the left side of my neck, from my upper neck behind my ears, down to the collar bone, are a bit sore all day and night long as if I had pulled a muscle. If I tilt my head up or to the side in a certain way and/or touch the swollen area just under my jaw I get a painful zap. Should I be concerned?
