Doctors with ME has a really good explanatory poster here:
https://doctorswith.me/home/what-is-me/
While I understand you can't just copy theirs, you might try something more similar. You might also ask their permission to use it in your organization.
Some thoughts:
1) Your poster is very busy and overcrowded with text. It needs to have fewer words for ease of reading. As
@Rufous McKinney says, the text is so small some of us can't read it. That's not want you want in a quick access document. Focus on the main point you want to get across.
2) You have two symptom sections, one in text and one in image. Choose one of the other. This will clean it up visually and focus your point. The text symptoms section confuses fatigue and PEM. These are the two most important concepts you need to get across to docs.
3) that inability to tolerate a posterior position. You are trying to describe orthostatic intolerance, so just say orthostatic intolerance. A medical person will know what this is. OK, snarky here, but we can tolerate a posterior position just fine-sitting down isn't the problem. the problem is standing up!
4) Your management section doesn't make sense. First sentence says CBT/GET and second sentence says nevermind, not CBT/GET. We understand what you are trying to say, but an uniformed doc won't. You will just come across as confused. You might say something like, in the past CBT/GET was recommended in the past. However, current guidelines and research show this is ineffective and potentially harmful.
5))
Diagnosis section is a total mashup. You need to explain how to use the diagnostic criteria. Again, look at Doctors with ME for guidance. link here:

You are doing a worthwhile project. Just keep editing!
