Roz, the younger son had shingles, and it flared twice. Went into the eye.
He had eye medication tube of something, I think to numb, and also the valtrex.

His eye was all swollen and face irratated, we thought it was allergy at first from up at work. It ended up being the shingles.
I took a few weeks to clear up and then a few weeks later, he swelled again,

He had shingles once before across his back. I think like cellulitis it stays in your body, a week area it can flare.
I hope you feel better,
Di
