Aslam o alaikum Sir my Father is heart patient and he is also diebetic.. Fromnthe last month or more he is having an infection just below the ankle on his right foot.. At first the infected area was too small but with the passage of time its keep growing. Earlier red deep spots were appeared which then came to upper layer and looked like filled with some liquid.. Then that surface becomes tight nd after sometime that upper layer vanished.. Then with a gap of two days red deep spots again appeared nd the process goes on.. I can send you a picture if required.. Kindly tell me what should we do now.. He never felt any sort of pain in it.
