Spur is a calcium build up on the bone. That has something to do with becoming flat footed, (I'm severely flat footed now, and didn't use to be)
ALWAYS wear shoes with arches! Don't go barefooted. Its took me almost a year of wearing shoes all the time. It was well worth it in the end. It sucked not going barefooted, hated to put my tennis shoes on all the time. Even in the house, trust me in time it will help although you don't think so. But ya gotta do, what ya gotta do. Now, to go outside I can handle wearing my backless tennis shoes with out my inserts.
Spurs are very painful, I had one for almost 2 years. Finally it got so bad I just couldn't live with it anymore. Some orthopedics will say get othototics made. But, for now Esther...get something called Powersteps inserts. (Footlocker carries them, but call around to some Ortho docs they will have them for sale too, although they are cheaper other places. They made the world of difference for me, my mother has them too and different doc told her the same thing. Oh, something else about having them made, I was told the ones they can make now that fit in regular tennis shoes run about 400.00. I was going to do it, but he said those were really good until I made a decision. Its taken care of me, so I never had the others made. Alot of times the ones that the docs make, you have to have special shoes too because they don't fit in your tennis shoes.
So far mine has been under control for 2 years. Every now and then I'll get a pain but it doesn't last long. I was to the point, if I had to get up in the middle of the night to go to the bathroom I almost had to hop or crawl. It would almost make me cry it hurt to bad. With me walking the floors at bingo, which I walked almost 6 miles 4 days a week. Plus with me letting it go for so long, I was walking funny and I've paid for that with my knee. Don't let it go, get something done.....but since the inserts everything has gotten better.
I felt so dumb doing these exercises, wouldn't do them for a long time. But after I started doing what I was told everything got better.
I had one in my left foot. I've had 2 cortisone shots. They said that the shot could last 3 days, 3 weeks, 3 months or forever. It helped for 3 months exactly, then it was worse than before. I went and got another shot. He had me doing different excise's, like getting something round, I used a piece of top railing from the fence (you could use 2 inch PVC). While your sitting, you roll you feet back and forth on it. It hurts to do, but it helps to stretch out the tenants in the arch area and dissolve the spur. Also, standing on steps back off the step just enough of the front part of your feet are holding you on the step. Stretch up (kinda of like tiptoeing but your still using the front of your foot and hold for about 30 sec, then back down. Then do it the opposite way, let your heels hang below the step. You know how people stretch before running, one leg bent the other behind...do that with no shoes on.
Here is a link of what they are...don't settle for a cheaper kind....BELIEVE me its well worth it. In time you will love these!
