first started with Jaundice, then colonoscopy with biopsy, had  an antibiotic shot due to having spinal cord infection  14 years prior. had to have a 10ml x  60m; stent put in pancreas, gall bladder and biliary to drain bile.  Also was dx with stage 4 CA of pancreas and liver.  Due to location cannot remove surgically or radiation tx due to location.  Have just completed round 1 of chemo and will restart chemo on Oct 22-24. Usually the symptoms are worse at night and keeps me from sleeping I have tried numerous topical creams  also benadryl but I dont like being groggy. unfortunately on medicare and hmo and it takes a month to get an appt with pcp>
I am sorry to say but from your description, I could not make out what your symptoms are that keep you awake at night. I assume it is the itching associated with jaundice. First, let me assure you that your treatment is on the right lines and your jaundice is likely to go down with time now that the stent has been placed. As the jaundice subsides, so will the itching. In the meantime, the only thing that is going to help is application of calamine on your skin before going to sleep (since that is the time when it troubles you most).
