I just found this thread cause the same exact thing as the OP happened to me just now. The tape didn't work for me but my mom suggested I run my foot under a strong stream of water (in the tub) and that fixed it. I don't know if whatever was there got out, but it doesn't hurt anymore. Occasionally I'm randomly feeling a little pain there, but it's not the sharp pain that made it so I couldn't walk. Go mom! I'm 41 by the way lol!
