Since I was 14 (now 34) I have had this outbreak on my kneecap and on my butcheek, but no where else. It is only ever about quarter size, has blisters on it, red all around, my gland on the left side at upper thigh is painful to touch and there are always red streaks leading away from the blister cluster on my knee. The one on my butcheek is never as bad as the knee. I have never really had it looked at since I was 14, I believe they said it was herpes, but cannot remember. I get pain before it comes all the way down my calf and get it about 1-2 times a year max. Is it herpes or shingles and what are risks/complications? The red streaks always scare me! What can I do for it? I cannot take Valtrez, it makes me sick and dizzy.
