I have POIS for about 15 years. 4 years ago the symptoms worsened strongly, so I decided to investigate further, and after consulting several doctors and after having done several tests, I took the EMG test, three times. All three times the result was positive. Diagnosis: latent normocalcemic tetany (aka normocalcemic spasmophilia). Symptoms: fasciculations, exhaustion, brain fog, dry skin, stomach upset, red eyes, chvostek sign. The same symptoms I have after orgasm.
Now, I don't think POIS is 100% reducible to spasmophilia: surely there is something more that causes us these horrible symptoms. However, I am convinced that there is a strong link with spasmophilia, and in particular with a neurological system disorder due to poor absorption of minerals by cells.
I would like to know how many poisers are EMG positive, but it looks like no one here has ever done it, except me.
It seems to me that too many people here focus on treating symptoms through unnecessary vitamin concoctions, and not on finding the causes (no offense to anyone) 
After working out with heavy weights I often have this uncomfortable irritation in my feet inner muscles as if something is pulling but not literally in the muscle but more in the nerve feeling
