You can get magnesium sulphate paste from the pharmacy (Magnoplasm). It is a thick paste that you warm up ( microwave or bowl of hot water). Apply to boil and cover with plaster. Also use lots of warm compress/bath. That is the best way to draw it out. Panadol or panadeine tablets may help ease the pain if it's really bad. Big Also try using salt to a warm bath. HTH.
