TKR

Hi, I had a TKR in Nov 1026 and things are looking up for me now. just the odd shooting pain but I can cope with that I don't limp anymore either. my problem now is the foot and ankle on the same leg I already had problems with arthritis in that foot but since the knee op it has got worse and walking with it is oh so painful and it is swollen in the morning and by the evening it looks ridiculously swollen. I am thinking of going back to the doctors and asking to see a foot doctor. I have done this before but to no avail just offered more pain killers which I do not want I don't want to be fobbed off again, has anyone any suggestions how I should go about asking the doctor for this as they make me feel I am being a nuisance so any advice would be more than welcome
