Well... it's not likely to be as serious as a broken leg. Chronic injuries/pain do get worse over time. Horses are innately stoic creatures who tend to frequently put up with a lot without lameness becoming blatantly obvious. Horses also run on adrenaline, which could potentially be why she walks badly but can still run without obvious lameness. There are also many injuries that can be intermittent... my own gimpy knee comes to mind. Bute is also bad for the gut & may be a good short term palliative, but not something that they should stay on more than a week or few.
So... hopefully over the last year you've been doing lots of study, to learn what you need to know. Some of the many things you may not be aware of is that your horses will need their teeth attended, yearly on average. They will need worming & hoof care 6 weekly and diet & nutrition are important subjects to learn more about too.
