Re: more back surgery or not?
I'm sorry to hear about your unfortunate accident.
Have you had any imaging on the lump/possible screw? It should be close to time for your first X-ray. It also sounds like knowing what that lump is might give you some peace of mind. (I clicked on the post since you didn't have any replies, then saw that Teri had already posted. Hi Teri!)
Kind in mind that L1 is going to have a tough time healing, since sitting on top of or below a fusion causes extra stress for adjoining vertabrae and discs, so be very, very careful and put that active lifestyle on hold so that you can get back to some of the things you enjoy later.
