Bascellex 50mg advice

Hi,  i have been on Bascellex for 9 out of a 16 week treatment plan.

The area being treated is my Vulva.

When i apply the cream (3 times per week), It burns my skin all night so i don't sleep at all on these nights.

My consultant suggested putting Emla on first as it's a numbing cream.  didn't work.

Do you have any suggestions as to what i can do to reduce burning and get some sleep?

regards
