Hi,
As mentioned from your other post,bacteria and metabolism of protein and amino acid may cause odor and the ammonia-like smell. Other  considerations include your diet, physical activity, stress, conditions like hyperhidrosis, diabetes and liver issues. The raw lines and bumps with pus may be caused by irritation. allergic reaction, infection and skin conditions such as intertrigo. Check with your doctor for proper evaluation. Take care and regards.
