See a / your physician as soon as possible.
you fall off and then you lay there for a second and make sure your not seriously hurt and then you get the horse and YOU GET RIGHT BACK ON! that is important. you don't even have to do anything except walk but it's better to just ride your horse again and correct whatever made you fall off.
if it makes the horse sore, no, if the horse is fine, then of course. you should ask your vet about it. by the way, this "dippy back" is called a "sway back" :)
definitely I ride all the time and my back still gets sore.

It is safer to have a saddle on a horse because it is better for the horses back, in some cases, and it is easier for a rider to fall off and get hurt with no saddle
