he didn't explain well. it was 10 yrs ago. i stopped using within a year because it was so confusing. also i have extreme ptsd. 3 additional cancers since original. in diff area (lungs, etc). Also at nape of neck & on scalp. Will call him tomorrow even tho have diff oncologist (diff area of cancers). I sound crazy--I am just so scared! What would you do--have refills? the med i asked about is clobetasol propionate oint, USP, 0.05%
