I don't think there is any cause -effect between cipro and urinating more or less. You probably are not hydrating like you should be.
Cipro will thicken stools and will most definitely photosensitize your skin to sunlight. You will, without appropriate sunblock, burn in record times if you go out in the sun, especially for a first time. You gotta double and triple up on the sunblock during summer months when on cipro.
I do remember reading that cipro can do a number on tendons and right when those concerns were widely being reported, I was at my peak in terms of going to the gym. I was always waiting for my ACL or achilles to snap on the treadmill, sending me into a writhing heap of agony, but it never happened. I have not been to a gym since Covid started.
