Living with Ross syndrome

In about 1978, I started read books with left eye closed un consciously, soon, my friend pointed out that my left eye pupil is larger than the other. We checked with a doctor in town, he dropped a drop in my large pupil eye, it shrinked, after sometime, it went back the same. There did not seem to be a cure. Did not do anything after.
In 2019, I noticed that after hiking, my left arm had sweat streaming down, right arm is dry, no sweat at all. Then, I noticed right upper back and right chest, no sweating either, then, right leg no sweating.
Doctor informed me about Ross syndrome, and told me not much could be done.
