I have a deep dullish fading and increasing pain in my left (only) shin. It is a couple inches below my knee and seems to be 3-5 inches in length when the pain is at it s height. It is as if it ebbs and flows. The pain is mild to moderate and very annoying. I am 51, fairly healthy, 5-7 , 130 lbs and fairly active though my diet could be better. It has been going on for a few weeks. It has not really increased in amount or number of occurances. I notice it mostly when resting. Either sitting or lying down.
