When I first dedicated myself to training for long distance running, I started getting some of the usual aches and pains (not knowing at the time exactly what they were). The first major problem was shin splints. I got to where it hurt so bad I was afraid my shins were fractured (not understanding that stress fractures are actually common in runners). Most advice I read told me to ice my shins and to take time off until completely healed. Well, I refused to do so because I had a 100-mile race I had already signed up to run. Slightly afraid that I was causing permanent damage, I kept pressing on until the pain began to subside after a couple weeks. Soon, it went away completely and never really returned. It was only then that I began to read about some injuries you can "run through." Let me warn you, there are some injuries that you simply can't run through. The problem I see is that there are conflicting points of view as to which ones you can and which ones you can't. I would like to say "listen to your body," but that isn't always wise. If you are too gentle with your body when it screams "stop!" you may be hindering your progress...but if you have a legitimate reason to stop and you keep rejecting your body's pleas, you could cause some long term damage.
My suggestion is that you:
1. Get multiple opinions (make sure your sources deal with running and other sports related injuries...even better, try to find actual running experts in the field).
2. Practice the R.I.C.E treatment regularly (at least three time per day)
3. Cut back your mileage slightly, and run (or jog or walk) at a more comfortable pace for a few days.
4. If you are still having pain that doesn't subside after a mile or so, take up to a week off (studies show that one week off will not noticeably hinder your training) and then try again.
5. Cross train (elliptical machine, biking, rowing, weight training, swimming...any exercise that will keep you fit but allow your troubled area to get some rest).
6. Be patient (some injuries take longer to go away than others, but hopefully you will have strengthened that area and the injury will be less likely to return).
