RE: Stiff Neck and Shoulders

http://www.youtube.com/omgseriouslywtf: I have been looking all over the internet, and actually stumbled upon your youtube channel while looking for an answer to my question.

my neck and upper back are very very tense. i can feel hard painful lumps up the back of my neck, and i was just wondering are these tense muscles that could be making me feel this way? my first thought was 'omg i have cancer! these large lumps are cancer!' but then i decided to try and be more rational about the situation haha

i have an anxiety disorder, so i am stressed a lot. i've never gotten a massage before, but my doctor did say my upper back muscles were VERY tense. like rock hard. i'm wondering if there's something i can do about this on my own? my posture isn't very good either.

how likely do you think the stress/anxiety and bad posture are to blame for this? what can i do? :/

thanks in advance for your help.
