Damn guys. I'm sorry to hear this. Black beard is right, they only treat symptoms these days. I use to be a medical teacher. I was given curriculum on telling me students to treat symptoms until the problem it's apparent, which in cases like yours, takes fucking forever. not always, but our system is fucked. what's more, they are so political with what they but and who they buy it from, sometimes they don't even have the best equipment. I hope you guys get better soon
