is surgery the only option for heel spurs? will they go away on its own?
You might want to check out the explanation in Health Central. Yes there are several options for heel spurs; heat, insoles, ultrasound, diathermy and surgery. Heel spurs are caused by calcification of the tendons where they attach to the heel and become inflamed causing pain. They can be 'broken up' to some extent by the methods above. Surgery is the treatment of last resort; first try the other ones - they do fix them for some people.
I was told that they would not go away on their own. In fact, they would probably get worse. I had to break down and have the surgery. First in the left foot, and about 18 months later, the other foot. It took a little while to heal, but they did feel better after the surgery.
I should say also, that I had already gone through the other regimens. I had the special insoles, the shots, the taping of the feet, all that stuff and more, before I finally had to make the choice to bite the bullet and go for the surgery. Just explore your options. Make sure that your doctor is a good doctor. Do a practitioners profile search on your state website. You don't want to just take anyone. Make sure you get a good, qualified doctor.
