I did took a couple of pictures, but they came out unclear. Even I who knew where to look didn't see much in them. I'm going to take the snake to a veterinarian tomorrow and hopefully this will be sorted out.

Thank you for answering. You might be right about the bacterial infection. Its eyes are clear, I saw the eyecaps myself on the last shed and they look fine now and it does not have an unusual muscle tonus. There are no other signs on its body. We'll see.

Best wishes!
