Anyone else get them when walking? Been walking the dog 3 miles every night and after about the first mile, my shins ache. Some days it is worse than others. Internet recommendations are new shoes, and walking less, evaluation by podiatrist. I have cut back to walking 2 out of 3 days and back to 2.5 miles. Seems to help but I still get a manageable ache from time to time. Shoes is next on the list since my podiatrist appointment is not for a couple of months. Anyone else have this and what has worked for you?
