Internal Blisters?

Anyone experienced that familiar sharp blister pain only to find no blisters on the bottom of their foot? During my 8 mile run Sunday and today's 6 mile run I started feeling like I was blistering on the ball of my right foot. However, my plantar skin is super thick and there are no blisters to be seen. If I press around on the ball of my foot I can feel where the internal blister is because of the sharp blister-like pain. It's not that bad and not enough to stop me from running but it doesn't feel great.
 
I had one like that once.

That could be one of two things. Either a bursitis, or a swelling of the fluid-filled sac around your metatarsals; or a Morton's neuroma (not Morton's toe), which is an enlargement of the nerves of the foot, usually of the nerves that travel between the 3rd and fourth toes. If that is the site of your pain, a neuroma would be my bet. It can cause numbness in the toes and burning at the ball of the foot and make you feel like there is a pebble or marble in your foot. Cause is unclear, and treatment involves rest, ice, and when you do where shoes, a wide toe box to avoid compressing your foot. Surgery is a last resort. Or you could have ran on a pebble and have a mild bone bruise.

I have had an internal one before. Can't see it, but doesn't feel right. I have used a sharp needle and pushed in at an angle to puncture it so it wouldn't turn into a callous or bigger blister later on.
 
That happened to me this year after a 5k. Normally I only run middle distance so I'm more used to my skin just peeling off from the high friction of the track. Which is much more painful, so I didn't really care about the blisters.

I thought they might heal up quickly, but instead the skin above them died and peeled back, only then did they heal up.
