Guttate flare while already on biologics. What should I expect?

Hi all, If you can relate, please share your experience. I'm 3 weeks into this ordeal and hoping for clarity on how much longer this will go on for, and what kind of recovery timeline to expect.

• I've been on adalimumab every 2 weeks for plaque psoriasis for nearly 2 years. Skin has been completely clear. Miracle cure for me, personally.
• I caught strep throat 4 weeks ago, and cleared it with antibiotics 3 weeks ago.
• Guttate psoriasis suddenly erupted over the past 3 weeks. I now have hundreds of spots. It's very severe. I've never had guttate psoriasis before. My skin is visually the worst it has ever been, even before qualifying for biologics.
• Biologics are still keeping my old plaques away, but doing absolutely nothing for the guttate. Is this normal? It's been 3 weeks and the guttate is still getting worse, not better. When do the biologics kick in again? What's going on?
• In a panic I contacted my derm, but I've been told to just wait it out, that it will clear over time. I've been rejected for UVB phototherapy as it's 'not compatible with adalimumab', and have just been given ointments instead. It takes me hours to apply the ointments to all of the spots.
• What kind of timeline can I expect. When does the guttate flare peak and then calm down?

Hoping someone has been through this and can relate
