Felt some mild rubbing sensation, almost like a blister, on the underside/outside of my left foot yesterday during an easy run. Not really painful. Took my shoe off after the run and saw a bulge/bump/lump right at that spot.
Wish I knew how to post pics on here. The lump is about an inch in diameter, I'm guessing right under the cuboid on the underside of the foot. Yesterday I would press on it and there would be the slightest discomfort, like pressing on a bruise. Today really no discomfort when I press on it. Movable. Firm, but not bonehard. I'm guessing fluid filled? Doesn't hurt to walk on and I'm pretty confident I could run on it without much pain. I'm thinking ganglion cyst.
Any ideas?
If it is ganglion cyst, I don't see anything that says you can't run on those barring great discomfort, but not sure I should risk it until I get checked out by a doctor. Thanks for the help.
