Ankle surgery 1 week ago - terrible pain at night

I was in your position this time last year. Bimalleolar fracture, plate and 9 screws on the left side and 2 long screws on the right (inside of ankle). I remember it felt like burning and swelling and was horrible at the time and I cried a lot. I took cocodamol and paracetemol to ease it but it didnt help the burning feeling much. About half way through the time I had to wear the plaster for I rang the hospital asking if they could check as it was very painful and felt like burning and maybe the plaster was on too tight, anyone they said to come in and they took the plaster off and it was fine underneath just a little red. I was expecting blisters and all sorts, they put a new plaster on and the burning came back the next day so i just endured it for the rest of the time. keep your foot raised as this helps keep the swelling down and try to keep it cool put a cool water bottle behind your knee or on the plaster through a tea towel so doesnt get wet. Hope this helps I'm walking 90% fine now. still stiff when ive been sitting for a while but it helps by giving the scars a good massage at my stage now. Back in all my old shoes though i avoid high heels i wear block heeled boots and theyre fine. Good luck.
