I had an infection on going into seawater around 10 days back.I applied UNDILUTED SAVLON on the wound three-four times. The infection is on the leg on which I have had three degree burns due to a petrol burn 20 years ago. Now I am applying T-Bact ointment on the wound,but the wound is not healing. I want help regarding the right medicine to use and if the wound mark will ever go from my leg?? Help me please...
