I had shingles for the first time last summer due to stress. They popped up on my knee, of all places. They didn't last very long, and luckily weren't incredibly painful. They kept me awake for a couple of nights, but not months as the doctor predicted. I used a calomine lotion with antihistamine to stop the itching/pain, and that seemed to work quite well. When I went to work, my pants would rub against them and irritate them, so I would wrap them up in a tensor bandage. I believe you can also get vaccinated for it now, so you may want to consider that if you worry about getting them again.
