Painful grafts in the cold. Is this normal? (Photo)

Hello, I am 16months post op and I am suffering from chronic congestion since my rhinoplasty, swell and pain. I am not in terrible pain all the time but when my nose is swollen it triggers the pain. Sometimes my nose is not swollen and even looks good. The cartilage grafts used are very uncomfortable to me and seem to be the reason why I am going through this, my question is : Is it common for grafts to become very stiff and painful in the cold ? To be outside for me in the winter is awful.
