I understand, but the sooner you get a handle on this behavior, the less time it will take to correct it. If you allow a horse to do something for too long without being taught otherwise, it will become a nasty (and dangerous, it sounds like) habit! I really think that, since you are babying him so much, it would be helpful for you to get a trusted trainer to come out, and work with you on some ground handling exercises - one of the best things an owner can do for their horse is ask for help. Even if you've had horses, this sounds like it is probably a new kind of issue for you to deal with (especially with the old injury variable, etc), and it would be to both your benefits for you to get a more experienced person out who can physically SHOW YOU (because trying to explain here, especially when fear is involved won't do you any good) what you should/can do, and show you how to correct the behavior safely... I think seeing someone correct your naughty horse and coach you through it will give you a new perspective. "New parent syndrome" is kind of a cop-out, lol... and YOU KNOW IT!!! Haha. I wouldn't worry about the farrier - unfortunately, many are used to horses who pull, etc... he may even be able to give you some great pointers!
