I'm surprised that they are being removed so soon after surgery.

I had a rod (looks like a 4" heavy duty hat pin ) removed from my big toe. It was to hold the toe in place after bunion surgery. Didn't hurt at all. I have a couple of screws in another toe that never healed after I broke it, and one of them is backing it's way out of the bone. I have a lump where it's coming out. I asked the podiatrist if he would just remove it and he said yes - but it has to be done at the surgery center and not in his office, since it involves bone. The heck with that - I'll keep the lump as long as it isn't painful!

You should be fine once the screws are out - no more pain.
