There is peace of mind after the visit. If your doc wants you to see him though, perhaps he thinks there might be a problem.
I had an ultrasound done by my cardiologist last year because I had chest pains related to a strained pectoral muscle.
My GP told me to see him against my better judgement.
Afterwards I found I have very clear arteries and It made me feel fantastic to know.
I feel the same way after getting my retinal photos done. It's like letting go of a lot of saved up stress.
When I had my kidney transplant, my transplant center required every diabetic of over 25 years experience to have an angiogram (a stress test was deemed to not cut it - not accurate enough especially in women). I had no symptoms and yet required 2 stents. It was a relief to have that taken care of before a major surgery. I didn't want to have an attack on the table.
I would say go for it. If you are fine, then peace of mind will be your friend for quite a while. If not, then things can be taken care of. A lot can happen in 5 years.
