I looked up the symptoms on the internet and it appears the swelling may be related to his liver problems. The increased morphine and steroid intake this past week may also be responsible.
I too am seeing the GP. Have developed a very sore throat/trachea over the past 3 weeks, which may or may not be due to stress - but it needs seeing to as I am finding it very painful to speak.
We are fast becoming a pair of old crocks!!
