Is head banging hazardous to my health?

I am the front man for a heavy metal band that is steadily growing in popularity. During shows, the whole band head bangs, but I seem to go a little bit harder than everyone else. Every morning after a show, I wake up with stiffness, soreness, and slight swelling of my neck and upper shoulders. Lately, I have been thinking that maybe thrashing my head around as if it isn't connected to my body is a bad idea.

My question is this: Does head banging cause any permanent injury that I should be concerned with? If so, how could I head bang differently to lessen the injury?


Is my vegetarian diet making me feel tired?

I am a vegetarian and frequently feel like it takes a long time to "wake up" in the morning and some days I feel like I never quite get there. I can't help but think this may be diet related. I went to a doctor for a test for anemia which was negative and I always try to get a good nights' sleep (six to eight hours). In the past I have tried to gain weight and failed miserably. I remain a little underweight but get a good deal of exercise each day. Any ideas?


Is it possible to reopen a closed piercing?

I have two piercings in each earlobe; however I have not worn earrings in the second set of holes for several years. Recently I tried to insert earrings into the seldom-used pierce holes. One earring went in with no problem, but the second did not go through after several attempts (I actually gave up because my last attempt bent the earring post). I have tried inserting other earrings but they also will not go all the way through. Is this something I can fix myself? Do I have to get the same hole professionally re-pierced? Will there be problems with scar tissue at the site?
