I went through immunotherapy several years ago, for an iatrogenically induced issue which angers me more, and I think it permanently damaged me. I was quite sick for a while after and have never felt "the same" as before. I know that's vague and easily dismissed but it's as if the side effects of the treatment never went away. I also just spent months and a LOT of money on multiple biopsies apropos of the post's title, one of which got infected and created a whole other level of pain, stress, and cost, for a misdiagnoses. I never needed to be cut up and infected. This happened to me long ago in a more severe way with surgery as well that disabled me. Misdiagnosed by multiple doctors, spent tens of thousands, worse off. I would have had a much higher quality of life overall had I never gone to a doctor in this country. They have never gotten it right from small to big issues, and ruined my life in the process. I guess I need to just learn my lesson that the system can never be trusted here. But it's hard when you have pain or problems and want a solution. In my professional and personal experience the potential negative outcomes are always massively underplayed to patients. Medical errors/misdiagnoses are the THIRD leading cause of death in the USA. If I had been properly informed about any of the big issues I suffered I would have never agreed to "treatment" and better off for it.
