Foot injury while swimming??

Interesting.  I think I had the exact same thing happen to me today.

I was putting on my sweats after my swim and my arch muscle basically seized up.  It seized as I was extending my foot to get my sweats on.  I got the foot through, looked down and could see the arch muscle spasming.  After a few seconds of intense pain, it just then went away.

Although, even though I'm new to swimming, I've been running for 2+ years w/o the slightest indication of Plantar fasciatis (sp?).

I'm also curious if this has happened to anyone else and what helped...

Thanks. 

I was having this problem last night in the pool!  It was like a charley horse and I could see the spasm through my skin.  I mentioned it in my log today.  I had been on the bike and running prior to my swim, so I think I may have been dehydrated.  Then the water was really cold, too, which felt particularly awful.  I went in the hot tub and put a jet on it.  (It really hurt, but in a good kind of way when I did that) When I got home I rolled it on my "tootsie roller"--something I got from PT as I had surgery on that same foot in October.  I also drank alot of water and ate some Shot Bloks.  It is fine today, for now.

I rolled my foot over a tennis ball last night, that seemed to help.

But I ran today and noticed odd feelings now on the arch in my other foot.

At this point, my mind is just f-ing with me...
