I do run, and have run regularly for 27 years. I started when I was 24. I do know that a runner should run facing traffic and I do not get annoyed by runners, since I am one. I would buy a reflective vest if you ever run at dawn or dusk, or in the dark. Running stores have very light weight ones that are not a problem to wear. I sometimes run wearing a headlamp, but that's when I'm running on cross-country trails.
I am lucky to have always had either dirt or pavement trails for all or most of my running routes. Even though the dirt trails are uneven, they are easier on my feet and joints by far than concrete or even pavement.
I have had occasional experiences with numbness, even where a whole leg was mostly numb. I never found the cause, but suspect that it had to do with my gait. If I had a pain or stiffness somewhere it would change my gait which led to a nerve or circulation problem.
I agree with having your shoes checked out. A good running store will analyze your gait and make sure your shoes are correct for you. You might want to warm-up and stretch more before a run (I am totally guilty of never doing this). You might want to get a deep body massage and be sure to tell your person about this experience. Or, visit a chiropractor for an adjustment.
Running is an impact sport, but that is not all bad. One way to prevent Osteoporosis in old age is to continue with an impact sport, which forces our bones to stay stronger.
I don't buy that running could cause something like a prolapsed uterus... Here's what the Mayo clinic has to say about that "Pregnancy and trauma incurred during childbirth, particularly with large babies or after a difficult labor and delivery, are the main causes of muscle weakness and stretching of supporting tissues leading to uterine prolapse."
So check into the suggestions you are getting, and you might find that a short break is part of the solution, but don't give up running!
