I considered that. The tightness is till there and is still sore to touch. The redness has gone completely after a few days of antibiotics and the burning sensation has disappeared. I will keep my eye on it. My calves and ta have always been "biggish" and always tight. I'm not much of a runner so shin splints are unlikely. I have also just put on a stack of weight and size. See how it settles in a week. The doc said it looked like cellulitis, but was perplexed by the lack of a puncture or infected hair follicle to introduce the infection.
