Nope--I didn't have an angiogram because I REFUSED to.
You are going to because you need it to convince you.
Classically, CSR comes from stress--the stress hormones cause the fluid buildup. And you are, temporarily, looking through a gel. The fluid under your retina is not exactly H2O--it's thicker, serum. Hence the "serous." If you could feel it with your fingers, which you cannot, it would be thickish and a little sticky. But it's part of the body fluid and given a chance the body will absorb it.
Stress does all kinds of things to one's body: raises blood pressure and heart rate, gives truncal (abdominal) obesity, causes CSR.
How about using this time to work on your stress: meditate, do yoga, exercise aerobically and, if needed, seek counseling. Avoid stress if you can.
