Marathon runners and joggers are very familiar with Plantar Fasciitis. The constant stress and strain that is placed on the Plantar Fascia during running can cause micro tears in the Plantar Fascia which leads to Plantar Fasciitis. But can you run with Plantar Fasciitis? The answer is yes, but your plantar fasciitis will most likely not improve. As a runner the best treatment you can give for Plantar Fasciitis is to take it easy for awhile and allow the Plantar Fasciitis to heal.
But what if you want to keep running. Is there anything to do to make the pain more tolerable? Yes, you need to stretch out your heel every day a couple times a day. Specifically before you run, stretch. Rub your foot over a pop can. There are all sorts of stretches located all over the internet. One of the best things you can do is get some shoe orthotics or insoles to run in. Here are a couple examples of orthotics or insoles I recommend for runners with Plantar Fasciitis:
But what if your race is in a couple of days, what can you do? It takes a couple weeks for insoles or orthotics to be effective for Plantar Fasciits. One thing to consider if you need immediate relief is to see a Podiatrist and get a cortisone shot. That should provide you relief for a 72 hour period when you will be able to run. Consider getting some socks made specifically for Plantar Fasciitis like these. Those can help reduce your discomfort:
But remember at all times Plantar Fasciitis tends to be a chronic condition. There is rarely an easy answer to the problem.
