question about pilon tib/fib fx

I am an RN who joined this to ask a question but I think I accidently joined as a PT. Anyhow my question is... I fx my tib/ fib (pilon fx) and had ORIF with 2 plates and 11 screws on Nov 18th. I injured it by falling down 13 stairs in my home. I am now having pain over the malleous bone and I am thinking it may be the plate I am feeling. Can wt bear without much pain in cam boot but have terrible pain when walking in shoe but only over malleous bone. So frustrated as my ROM is excellent. Surgeon said he would take plates out 3 mos post op. Is this too soon. last x-ray showed fib healed and tib almost there he said. Go back on feb 8th. Do you think pain could be from plate and is 3 mos ok to remove plate? Worry about stiffness if too long in boot. Thanks for any advice!
