Not all medical dx's are accurate any more than are the MI ones even from what we would think are qualified hospitals.

Have a friend who one university hospital suggested ALS....at Mayo they did back surgery he never recovered from but continually got worse & they refused to consider ALS saying their tests were unconclusive. Yes, he is dealing with ALS.

I went to UCLA'S psych hospital. My insurance wanted a dx so they knew what treatments they should be paying for....this wasehile I was working & had good insurance back in the 90's. UCLA couldnt even figure it out thoygh Im sure they put something down to appease the insurance company. It ended up many years later being major depression & anxiety though none never grasped the REAL situstion behind why it was do major....just figured that out almost 20 years later & go figure it was an undiagnosed condition my H had & my own dad had that I had been struggling to deal with 40+ years of my life & the loss mf my career was the trigger to it finally effecting me becsuse I no longer had anywhere to escape to & to top that off, one T I wrnt to thought there was PTSD thrown in, not just from the final trsuma I had gone through. He explained how all the different experiences I talked about were traumatic including the one I was going through at the time

MI's are very complex....much more complex than what a simple dx at a hospital can even imagine. I hold NO VALUE to dx's grim my own personal experience but needed something in order slso to qualify for disability which was approved immediately at the time because I was so messed up.

Life changes & things resolve for some DX'S. others need good monitoring all one's life....yes.

As for why your DX didnt show up on your ER file, it dependson whether it was computerized & whether the information was actually availsble to the ER. Most times ER work is about a one time crisis situation that you are there fir at the immediate time & that is ALL the ER MD's are focused on at that time....treating & stabalizing or determining a need for psych consult to determine if IP is necessary where the actual records would become available. Hard to say how the actual ER works that you went to. But it is not normal for thrm to access records that are filed away in writing & not computerized for easy access because ER'S are usually overloaded in the first place just trying to treat the emergency on hand & accessing record information is ususlly not possible especially if the records office is closed at the time.
