By the time I have time to translate into Spanish, I will have compiled nearly 9 pages of findings on his health issues. The fact that he stated on Moonwalk that they had to stop the Destiny tour because he had a "sore throat", then pleurisy, when he almost drowned near Jermaine's house, then too many accounts of "laryngitis" and "sore throat", then information here and there about inflamed vocal cords during the Bad tour, in '91 he had ribcage inflammations that kept him out of the studio for six weeks, the incident with not being able to reach higher notes like he used to when recording Keep the faith (and he was a master at this, he mostly used his head voice since he started singing and not falsetto, which is easy), the fact that even a month later, when the Dangerous tour started, he was looking for a throat specialist in London (but his doctors, as I see, were more busy giving him painkillers), in '83, besides that doctor Klein, he also had Metzger, a rheumatologist (who needs a rheumatologist at that age?), stiff hands when he didn't even have 40 years old, and so many other things. I bet the movie won't show this struggle and just blame it on his upbringing and scandals...
There are also rumors among his colleagues that he needed oxygen tanks, at least during the History tour. And prior... That makes me think there's some truth to that "oxygen chamber."
I'm very detail-oriented, and I noticed, for example, something like stiffness in his hands later on and a scar on his right hand during the "Man in the Mirror Bad Tour Minneapolis" or, I don't remember exactly, during the US dates. It seems he had at least one surgery for carpal tunnel syndrome.
