Directly behind my ear, approximately mid lobe, right side, is slightly swollen and very painful. I don't know if it is a gland or a muscle or what. I've been massaging using reflexology, those areas that correlate to the area. It is painful on those tissue sites as well. What would cause that suddenly? I thought it might be stress related, but most of my stress is carried in my shoulders. I have a massage scheduled in 3 days. Should i cancel it or will it affect the swelling and cause more pain?
