You got kicked in Feb 2012? And there is still a tender spot?

I assume they did x ray & maybe other imaging to check everything?
Might be wise to have some follow up imaging to verify, before settling, if that hasn't been double checked.

Do you have a work comp atty on your case?
Usually they don't settle until you are more or less at maximum improvement, or stable at least.

Is there talk of keeping long term medical open for this ,or just a lump sum payment and nothing else?

A lump sum sounds nice, but you need to do a loss of income, treatment & rx costs projecting into the future. It's a complicated situation so a good atty on your side might be worth it.
