Erin,

I have knee pain and cracking but I have also had arthritis in my knees since my early 20s. When the arthritis was dx'd my Dr. said it was due to all the falling I had done. I fell alot as a kid and never outgrew it.

Kneeling down has been known to trigger the pain in my knees. I rarely kneel anymore.

I usually get relief from Advil.

Spasticity causes tightness and joints can hurt as those muscles are being pulled.
