I had the Levulan Kerastick + blu-u. I was not counseled as to the time it would involve in the office nor was I informed regarding the downtime after the procedure. I may have had a overreaction to the treatment as my face was very painful, swollen and oozing. I am post treatment day 5 and still have pain, tingling and sensitivity. If I were not retired I would have had to take at least 1-2 weeks off from work to recover and was not informed of that possibility. My advise is to improve on the pre-treatment patient education before arrival to the office. I was most surprised about the level of pain that I had on day 2-4post treatment rating a 9 out of 10. I used the recommendations of cold packs, diluted vinegar, moisturizer , advil helped reduce the pain at least to tolerable while cool pack was in place. In addition I have not been in the sun for 5 days.
