Prime how are your joints at your age ankles knees etc.?
Until recently, they were fine.
Sometime back, I started having issues with sciatica, which now affects my entire right leg and foot. Initially, it would flare up only when I was driving long distance and I could relieve the cramping in my right hamstring by getting out of the car doing some, squats, toe touches and often just by walking some. More recently, an MRI revealed that I have a torn meniscus in my right leg. I've seen a doctor regarding this and will probably have arthroscopic repairs done shortly. It seems possible to me that my gait is off because of the pain from the torn meniscus which somehow has aggravated the sciatic nerve causing cramping in my calf, pain in my shins and numbness throughout my right foot.
In other words, my right leg is a mess right now.
What I have which is definitely age related and perhaps somewhat genetic since my mom had arthritis pain is osteoarthritis in my hands, back and knees. I doubt this condition was caused by weight training. If fact, I think weight training has actually helped keep it at bay. Supposedly, resistance training is recommended for people who suffer from arthritis.
