I've never had an outbreak that I know of. I get muscle tics sometimes, mostly in my legs in arms (but I'm also active). I get canker sores throughout the year. I sometimes get a lightheaded event 2-3 times a year. I've noticed some small red dots that appear and disappear within 48 hrs. Smooth, don't itch.
Is it herpes? I don't know. Before I knew I had it, I would just chalk this stuff up to dehydration, overworked, muscle trauma, etc.
For your back/leg pain, are you sitting at a desk a lot? Are you a runner? Do you stretch? Being an asymptomatic carrier, I've been learning to blame herpes last, or never. Back pain could be anything. Stretch, strengthen your core, etc.
