You get bucket licks which help clean up orf, magic stuff. We sprayed dilute iodine or antiseptic spray on, but the buckets did the trick. The lamb that's not doing so well may have a secondary infection, so may need antibiotics (antibiotics does nothing for orf) You just have to let it run it's course.
For yourself you just have to let it run it's course, but watch for secondary infection.
I had orf on my thumb once and I kept it wrapped up with antiseptic cream then milk filter wrapped round( make shift comfortable bandage.)Keep plenty of cream and padding on it especially once it starts to go sore and I had the thumb of a plastic glove on top to prevent more infection. Knowing you can't do anything I did not go to doctor but after reading online and I started to get v faint red lines on my arm and realising this was serious I went to doctor and got antibiotics as infection going up arm and got supply of padding and bandage and having to go back to nurse to get it checked and re banadaged. Wasn't so sore after antibiotics killed off infection) Doctor had to google it as well luckily one of the nurse's had seen it before. I was star attraction to every doctor and nurse in the surgery.
To start with it's not sore just a growing bit of hard skin but then gets bigger and blood vessels appear throbing and painful ,loads of soothing antiseptic cream and padding helps. Then the swelling suddenly goes down and not sore but just left with deformed skin but that eventually peels off and then your back to normal again although new skin tender for a while.
SALT! OWEEEEE. I also dipped affected thumb in diluted iodine - soothing as is loads antiseptic cream like germolene but any would do.
