There was a definite change to my pain levels and waves. I did it and got through but wow I should have used my cane. 5 more weeks and I can start treatment again. It was a nice day up there. The winds were calm, and it wasn't any colder up there but still I was hurting big time. Then people were crowding me and some brushed my left leg and I almost went down. Not fun when you're pregnant and have a 2 yr old in your arms because he wants mommy. Just so yall know for me elevation does make a difference.
