Self medicating

Not at all sure where best to post this, so feel free to move..

Am at the end of my taper with Prednisolone for aggresssive lichen planus.
This week have arrived down Saturday to 5mg.

Its not enough. The rash comes back ( not that it ever went away this time entirely) with a vengence.

Last night went to bed with it all rasing its head in my vulva,anal, mouth, tongue area. My hands are getting like Rhino hide and cracking.

None of the above is as bad as it can be I assure you.

I was told by the Dermie 6th Dec that it should take 8 weeks if drug induced ( Mepacrine) to be out of my system.
Meanwhile my Rhumatologist saw me a couple of weeks ago and has suggested that its possible after I finish the steroids to go into a flare. Then he suggested that course action is to put me on low maintainence dose of steroids for the flare if needed.

So this is where Im at:-

Desparate last night, I took 15mg of steroids thinking ' I cant cope so Im going to self medicate upwards.
I wanted to stop so the Dermatologist who is taking a biopsy next Saturday could see almost 3 months later its looks pretty awful.

The toughness and general inflammation makes my hand skin unable to stretch properly as I reduce the steroids and all along the life lines and all the other lines I get cracks where it literally tears apart, so infection is a worry also. I have to use gloves for everything. Cant wash myhands as it so painful.

This is futile as the evidence without stopping speaks for itself so Im not sure quite what I was thinking.

My son has scarlett fever so he's sleeping in my bed...so justifying the re uptake of steroids was a no brainer really.

Im going to see the Dermie I know...but Im worried about how long this is taking to come out of my system. Ive read reports about how geneally lichen planus takes its course but nothing for an aggressive drug induced.

Then there is the concern about being longer than the original plan on steroids.

Any input gladly received.
