Question: Hi I have a red purple rash on my penis head glans with white tenticale like lines on left and right side. It started about a month ago when I noticed small white faded spots one on left and one on right side. There were no other symptoms except a two day itching under penis glans. I allso noticed when taking shower that there were small white dots under glans of penis on right side but I didnt pay much attention to that no red color no discomfort. After itching a day or two later came a light dull pain on the same place and it was present almost every day and I could feel it from time to time. After that i started to notice light red color on glans "head of penis" around where white spots where before present "head of penis" the color became more and more intensive and it was starting to turn purple also at the same time i noticed that there was white rash starting to appear near where the pain was on foreskin of penis. I don't know exactly how to describe it but it was watery like but it was skin there was no discharge. Soon after pain sparkling tingling felling became present pain was still present from time to time on the same spot but tingling and sparkling was present around corona and on tip of penis no itching. After applying canasten cream 20 mg symptoms like sparkling tingling etc went away pain as still present although it was not present as much. After 3-4 days of treatment rash on foresking became smaller but still noticable. purple color went away and red color beacme more light but white tentical like lines became more visible . After a week now it seems that the rash is a bit smaller but white lines are a little less intense but still visible allso the pain seems to be present from time to time. also sking looks dry like and skin on rash is very smooth. If I touch rash there is no pain.

Is it normal that after a week of treatment rash is still present?
