That really sucks.... I had a heel spur once a few years ago, I didnt even notice it it came on so gradually, then one morning I woke up and POW. Couldnt even stand on it. 3 days after that (a brutal 3 days) I went to my chiropractor, I am not even shitting you, but within 24 hours the pain was completely gone. All I had to do was stay off dairy (milk and cheese) for a few weeks and all was well.
Trust me man I know what you are going through.
