I had some slight swelling behind my left ear on Monday, on Tuesday my jaw and left side of face was badly swollen. I went to the doctors in the morning and was told it was Mumps. I have been off work for 4 days now. The swelling spread to other side of my face and my neck (particularly around the ears and under my jawline). It is very uncomfortable, painful to chew, I have experienced some headaches, back pain and hot and cold flushes. Although I have been taking OTC drugs which have helped quite well. Today the swelling is the same (I still look like a hamster), but physically I feel fine. Is the swelling likely to go down now? Can I return to work soon? Is it likely to be Mumps or something else perhaps? I am 23, female, and completely healthy otherwise.
