I've just noticed a few small knots around the neck area - behind the right ear, base of neck, left side of neck. I have to tilt my head a bit to locate them, but at different angles they're more pronounced. No pain, just a little achy if pushed/prodded. I've been under a lot of financial stress, but have also been working out strenuously - including abdominal exercises that engage the head and neck - and I've been straining to see the computer/or read b/c I need to replace my contacts. Could these factors be the culprits? I am 5'7", 42 yrs old, and 152 lbs. Trying to lose last of the "baby" weight (3 yrs old now). Exercise regularly, in fairly good shape as far as I know (aside from prior fertility issues).
