Have a nasty boil type thing on the back of my shoulder. I first noticed it on Wednesday but I’ve been at Glastonbury and haven’t been able to do anything with it! I have managed to scratch the surface off, which isn’t ideal but don’t know what’s best to draw it out as you can’t get mag sulph paste anymore. I have sudocrem or a salicylic acid pore cleaner, fellow sporners what do you think will best draw it out??? Pic in next post and I promise to update!
