Any advice gratefully taken. I've been up all night with a pain in my gum and there's a big lump there. Defintely an abcess. I'm self - isolating due to covid19. What can I do to treat this at home? Painkillers aren't touching it and I can't eat or sleep. Any ideas or suggestions would be very useful. I'm in so much pain I feel murderous. Please advise me? AiBU to think I can treat this at home?
