Hi there ~
A difference is the size of pupils is not uncommon. It is also not affecting your vision and so I would advise to stop worrying about the size of your pupils. I am sure it has also not come up in normal conversation. I am glad that your stress test
was negative and your costochondritis
is also better. If your fibromyalgia
is giving you problems, I would advice you to see a qualified psychiatrist
. Deep breathing and relaxation exercises are helpful in these situations.
Take care and have a nice day.
