Hi Ray and welcome
when robs cancer reocurred the worst syptom he suffered was massive facial swelling.His lips were twice the size,his eyes were nearly closed it looked absolutely terrible.When he was taken over by the palliative care consultant he started him on a very high dose of oral steroids.within 24 hours the swelling had gone,and as long as he took the tablets it didn't come back.when he was in the hospice they reduced the dose slightly because he bacame a little angry which is a side effect of long term use of steroids,but this was a small price to pay for the relief he got.
I hope you can find some relief for your problem,but topical steroids is not the answer i am afraid.
