I went through a MRI and Neurology tests a month or so ago. I have disc issues in 3 areas along with calcium build up. The neurologist thought my tingling in my hands was nerve entrapment in my elbows but when it acts up I can go top the chiro and it goes away. Apparently when the MRI was taken everything was in perfect alignment. This morning not the case. I have a bad lumbar disc that causes bone on bone and right knee pain and foot tingling. It's hell to get old. I wonder if marijuana would help? LOL
