Just thought I’d step in here for a sec and mention that my AN is definitely cause tendinitis which I experience every day for multiple hours. It is definitely affecting my vision, causing my vision to go in and out of focus I did go to a ophthalmologist and they found nothing wrong with my eyes, agreeing that possibly my vision problems were caused by my AN so much to my dismay, but not my surprise when you autonomic nervous system has a mind of its own. You come to expect these inconveniences I know for a while. It was like I should treat this symptom with that this symptoms something else but it doesn’t work like that symptoms keep changing coming and going in a funny way, I try not to challenge them anymore. The medication I use works most the time the pain seeps through some of the time do the best I can find a strange humor in all of it.
