Sore sheeps udder HELP!!

[Gulli]

Had one like this this year, mastitis in one side so I lifted a lamb off, and she developed a sore like yours has @Becky1992 so I took the other lamb off her until the teat healed up and then chucked him back in as he wasn't cooperating with the bottle and the pair of them are away to grass now with no problems.
If there's milk both sides I would be tempted to let them in for a drink a couple of times a day and keep spraying the teat until it heals and she should be fine then

Wash your hands really well after or use gloves! Not an expirience you will want to repeat if you get it on a not intended area

Antibiotics and pencillin

Black bag does this coincide with cold winds and frosts?

Give it antibiotics, it's knackered as an udder, it'll go cold, most probably slough off. If it gets really bad it may be worth cutting into it to allow it to drain. BUT ONLY IF IT GOES STONE COLD, it's dead then with no feeling. Definitely a cull ewe if she survives.
