Unexpected (wonderful!) NSV

I have had knee problems since I was in Jr High and at a normal weight. In the last few years my left knee has hurt. so. bad. Every day. Especially in the morning going down the stairs. A month ago, I was nervous carrying my one year old down because I thought I might fall. I'm only 28! I have hated that I am young with knee problems. What would they be like as I got older? I have always been nervous about exercising because A) it hurt and I worried about injuring them further.

I bought an elliptical recently and have worked up from 47 pitiful seconds on day one. To four weeks later I'm up to 30 minutes! And I don't feel like I'm going to die! lol

Yesterday I woke up and walked down the stairs completely pain free! It feels like a freakin' miracle to me. How I babied them and was scared to exercise. Thank God for ellipticals. Somehow it has strengthened my knee and made me feel like a normal 28 year old. I thought I had to suffer for life. I'm SOOOOO happy for this awesome NSV! I can even do squats now!
