I spent 6 days in the hospital recently recovering from hyponatremia. I was in the ICU for 3 days (unconscious until the end of the third day). My CPK level was 19,000 upon arrival (it didn't drop for 2 days) and my sodium was at 112 upon arrival (it got down to 110 at one point). There were substances I had taken the contributed to these insane numbers, but it was a combination of dehydration, drinking too much water (no electrolytes), being underweight (105 at 5'5", though my illness got me down to 98 lbs), and vomiting. I bounced back fairly quickly--I'm young and aside from a few chemical experiments I am quite a health nut (side note: I no longer use anything sketchy, including tobacco and alcohol, and I'm up to 108 lbs). I had no permanent damage (which is amazing), but I had a little tissue damage that I was told should repair itself.
It's been over a month now and I still have intense back pain (mostly upper). My hair falls out in large clumps (I have a ton, so it isn't noticeable to others). My skin is extremely dry and flakes off all over my body. And I have a red rash over my cheeks and nose. My hands and feet are swollen a lot of the time, too. In general, my body is just not quite right. I don't know if it's related to my experience or not. Anyone got any ideas?
