Contraction at Face due to Cold. Then!

4 years ago I was detected with Ameloblastoma and had my operation successfully done at CMC Vellore. I am fine since then regarding it. Go through my profile and current medication undergoing, I have stopped taking both tablets (Diane 35 and Met-Innovfol) yesterday I consulted the gyno who prescribed it and he told me to stop. I face a severe problem when I catch cold that is contraction. The area where my operation was done (since the upper left jaw bone and cheek bone is removed due to ameloblastoma), i feel severe contractions (untolerable) when I catch cold or when the the weather becomes excess cold. I travelled about 25hrs in train from Kolkata to Dehradun and due to the AC I caught cold, and I am feeling extreme contractions. What can fix this please help me. It becomes somewhat normal when I heat the region by heating pad but as I remove it continues.. I have to return from here and its again a 30hr journey. Currently I am at hotel but its un tolerable contractions pls help me
