Thanks SB
Neither methotrexate or prednisolone work for my DH these days, even though he can't/shouldn't take them when TTC.
Off topic- have you tried elocon? Think that's how you spell it.
DH uses it in his hair-liquid, and on his face-cream.
It works almost instantly.
It is a steroid cream and best prescribed under direction of a skin specialist.

So sorry you have to suffer through it
