Ouch!

Well after what at least 2 months of walking, I finally realized today that the pain I have felt in my lower front legs all week is shin splints!  It started Monday but I thought it was just from not walking since Thursday.  But Tuesday was worse not better, Wednesday was okay, yesterday finally didn't hurt, but today, my shins were on fire!!!!  Phyllis said maybe it's shins splints.  And then the light bulb went on!  Ugh.  I hate it.   So our 4 mile walk today was really not a record breaker cuz I just couldn't walk fast without pain.
Does anyone have any idea on this other than just healing?
