My current MEPS doctor is passing my case onto the Surgeon General? What does this mean? How long does this usually take? What can I do?

That depends in what services Surgeons General?... because ..they don't want to report a training death..because that requires alot more time. I work for a military hospital and have worked with surgerons general and deputies, so my opinion....is that they probably will send it through the medical chain of command to review and opinion fron the chief of nursing, chief of cardiovascular, then chief nurse of your particular service and then probably final word would come from the DSG or deputy surgeon General of your service, who would be the chief doctor or nurse of that service. Army Navy or Air Force....then it will trickle...mind you trickle back to you ..I would modestly estimate 4 to 6 weeks .....something like this I'd like getting a second , third , forth...etc opinion.and then the final word...and they can say yes..we are comfortable that we have the medical professionals to keep him under medical surveillance..or we are not comfortable ..because your condition is farther along that the stress of basic training would allow....but all thatvwill be laid out by each department or link in the chain amd final decision. So....don't give up hope....like my mother always said. Hope for the best...prepare for the worst

Try the SMR State Military Reserve or State militia if things don't work out.

Probably not a good thing, but I don't know all about the time frame
