Male 30yrs old, diagnosed with MCTD 5 years ago. After a two month stay just in the town of Bochstein/bad gastein, with out even visiting the caves and I haven't taken medication for the pain since, nearly 9 months ago! Results have been nothing less than incredible. I didn't even know about the caves before I went there, didnt even go to them whilst I was there but there must be radon in the Air or water, who knows and I sure as hell dont care. Not another hippy buy into anything fool, but would highly recommend
