Biologics

Hi. I have had Long term severe psoriasis about 90% body coverage. I’ve had light therapy,creams,tablets, first biologic Humeria worked for a few months and it came back with a vengeance. On second biologic now Cosentyx done the 5 weeks now on monthly. It’s working yay. But my dr had said this is it I can only have two biologics. I have read other people (mainly abroad) are on 4th etc. Has anyone else been told this? I’d really appreciate any help. I’m due to see him soon. I don’t like having him as my dr but have no choice. He has bothered to look at me twice properly in 6 years. Normally he looks at my hands 🙄 He left me in do much pain A&E were going to keep me in as I could barely move. Thanks for reading this epic tale 😂
