It's possible corrective shoeing by an expert farrier can help the horse a bit. It's definitely worth looking into. Note I didn't recommend just any farrier, but an expert farrier.
You may well be dealing with bone changes from an old injury, or simply from hard use.
I just want to caution you on the use of the anti-inflammatory. Learn all you can about this class of drugs and their use in horses. Horses are very susceptible to ulcers, and overuse of anti-iflammatory drugs can actually cause ulcers. Just be careful and use the drug properly.
If you are so inclined, you may want to talk to the person you bought the horse from. If you're not extremely attached to the horse, you may be able to work something out with the previous owner. On the other hand, it might be a case of buyer beware.
Good luck to you.
