Enstilar foam

Hi Looking for a little help or advice. I recently was referred to a dermatologists at Bolton Hospital after seeing my GP. The last time I'd been referred was in 2012 in which I was given light treatment after suffering from chronic psoriasis. The treatment worked brilliantly all until the last 12 months. It had returned quite quickly so I went to my GP who reffered me again. Whilst seeing the dermatologist they recommended light treatment again but is a 5 month waiting list. In the meantime they asked what creams/ointments I have/had been using. I always use to get dovobet gel which worked however the application was very long and draining especially when having psoarisis head to toe and trying to apply it twice a day. I explained to my dermatologist that I needed something that is a lot more quicker and suited my hectic lifestyle. I work over 8 hours a day and spend 3 hours as well travelling to and from work. With a girl friend who is over 8 months pregnant I found it difficult and expected it would be even more difficult to find the time for dovobet once our baby has arrived. Baring in mind I've been using dovobet for the last 8 years of not longer. He suggest Enstilar foam spray for 4 weeks and psoriderm cream (the smelly stuff) for 2 weeks. I picked up my pescription and tried it. I can honestly say Enstilar it's the best treatment I've ever had . A lot easier to apply and the results were as good as light treatment to a point that after 4 weeks I was pretty much clear and wouldn't even need light treatment in the end. I took the prescription I got from my dermatologist to my GP's asking for more of enstilar. The receptionist said come back In 48 hours to collect. The next day I receive a Phone call telling me that they won't re-prescribe enstilar and to use the psoriderm. I did as advised but the treatment is not working and my psoriasis is starting to flare up again. Not to mention the fact that it stinks, stains my clothes and cannot seem to rid the stench from me at home and work. I don't understand why they will not re-prescribe it again. I was given no valid explanation other than to use the other cream for 2 weeks as the dermatologist had suggested. The phone call was not even from a doctor. Has anyone else had trouble with trying to get hold of it from their GP. After suffering with psoriasis for 12 years I finally find something that works, suits me and my lifestyle and for once being a sigh of relief only to be told I can't have it. Any help of advice would greatly be appreciated. I'm going to book an appointment to see my doctor this week to question why however I have the feeling that they are going to fob me off.
