Aches and pains

Foot hurting. A tennis ball sized bump has appeared on it. Remember doc saying it's called a ganglion. Supposedly happen due to nerves getting all mixed up, whatever that means.
All of the foot aches though. May be cos I walk barefoot on tiles too much. It's interesting to note that while buying/ making tiles we look for beauty, strength , ease in laying it, almost everything but it's primary use, to walk on comfortably.
