DH has grown this. Tried squeezing, nothing. Tried lancing, a little blood. Feels quite hard around the area. No head, any sign of a head in the photos is a flash back from the camera. Any suggestions, no magnesium sulphate in the house.
The surrounding skin is actually quite red on that. It may need antibiotics. Probably best to draw a line around the edges and keep a close eye on it. In the meantime time try to draw it out with heat. Maybe a soak in a hot bath with Epsom Salts or table salt even. If it extends beyond the line or your Dh develops a temperature see a GP. Don't poke it again until you see a proper head though.
