Dear Dr chip,
no trauma and it's been about a week. I thought it might go away - just soreness in a patch at first on left leg, but now see slight swelling and soreness not abating.
Just one area from top of the knee in a kind of circle or patch on the inside thigh.
I recently suffered from a bulging disc lower back but that has abated and think it not related as this is more local on the outside as if reacting to a bite (tho large and not internal)
