Effective training can only come on top of a base of good health. PF is a nasty injury that can last months and leave you pretty hobbled. I recommend taking this seriously and not trying to train through it. Yes it is a major bummer to have your plans suddenly disrupted by any injury or illness. It happens all the time to athletes and some times careers come to an end because of it.
Be good to this facial injury. Take a proactive approach with therapy. Research it on the internet. There are some easy self help therapies you can do with out the help of a PT. Use the shot gun approach and try them all: Ice/heat, NSAIDs, Taping, Massage, and most of all: Rest. Treat it early on aggressively and see if you can kick it ASAP
For sure don’t carry weight. There is some likelihood that the ME may have been what caused this injury. I’d even go so fat to say that you need to stop doing anything that hurts it until you are pain free. I’ve known many folks who have had PF linger for years.
Good luck and be careful. Its a bummer to get injured. It is an even bigger bummer to have this become a chronic injury.
