    T sounds like you used slime. It does not work. It clogs valves. When you do get a leak, it can spread that mess all over the inside o f your tire. If you hate flats get Mr Tuffy tire liners. Personally, knowing what I THINK has happened, I'd trash it and put a new tube without slime.

    Replace the tube, they aren't expensive.

    Maybe it's just local, but Walmart is the most expensive place to buy tubes. All the LBS have tubes at least 25-50% less.
