Could a healing fracture of 3rd and 4th metatarsal cause intense pain in those toes? i don't remember injuring the foot to cause this.

Neuroma pain.: There could be a very good chance you have a morton's neuroma. It is a nerve between your 3rd and 4th metatarsals that can cause intense pain to the respected toes. It is worse with tight shoes on and relieved by going without shoes. I was suggest having it looked at by a Podiatrist. Probably not a fracture since there is no obvious trauma. neuromas are a common problem.
