Re: your epidural injections. I have had 3 recently in spine for thigh pain, and also noticed sudden problems with charlie horses...in calf. Also just happened to be tested for Cortisol levels with stim test and mine were so low the doc called in cortisone pills and wants me in for further evaluation. since she called I have looked online and found out that steroid injections can severly suppress adrenal function. NO DOC told me this at Spine Center. My endo is not sure this is the only reason, though, so I will have to see whats next...low cortisol levels can be dangerous, even life threatening, I am wondering if mine were low before that. And now wondering about the leg cramps. I am taking Magnesium too...just wanted you to be aware of that...
