I am 4mos. post treatment. I tolerated chemo and radiation extremely well, but one thing is concerning me. On the left side where I recieved more radiation I experienced swelling at the lower back of my jaw about 5 weeks into treatment. My RO wasn't concerned at the time. I last saw him early July. I am healing fairly well except this swelling has not improved and has deepened into an ache. Does anyone know if this should be cause for concern?
