Do any of you experience any weakness in your knees. It seems like lately, everything is going to my knees. I love to dance and when I began to dance, I thought my knees would fall off and had to stop. I am going dancing soon and I sure don't want to have to sit there. At least, I could dance a dance or two. This will be the first time since beginning Mestinon. My knees feel fine resting, but I have noticed when I walk, my knees feel funny. It is so strange. busybusy
