Hi Im new to this forum, my daughter who has a remnant pituitary tumour, she has also had radiotherapy, she has terrible pain around her face neck ear and jaw, they believe the tumour that is left is pressing on the trigeminal nerve. she has this pain every day, but when she gets a head cold runny etc, this pain goes, so now we are wondering if there is a problem with her sinuses. any help would be appreciated.
