What causes wounds to smell?

Pathophysiology Foul odors from wounds result from the metabolic by-products of anaerobic and certain gram negative organisms. Deeper infection (e.g. cellulitis, necrotizing infections) are not necessary for significant odor generation.

Why do bacteria smell?

When food goes bad and starts to become pungent, it is most often due to the growth of spoilage microbes such as bacteria, yeasts and mold. Odors can come from two sources: chemicals that are released from the food as the microbes decompose it, or chemicals produced directly by the microbes themselves.

What are the stages of wound healing?

The complicated mechanism of wound healing occurs in four phases: hemostasis, inflammation, proliferation, and remodeling.

What color should a healing wound be?

Healthy granulation tissue is pink in colour and is an indicator of healing. Unhealthy granulation is dark red in colour, often bleeds on contact, and may indicate the presence of wound infection. Such wounds should be cultured and treated in the light of microbiological results.

Why is my healing wound throbbing?

This arises from damaged tissue. Signals are picked up by sensory receptors in nerve endings in the damaged tissue. The nerves transmit the signals to the spinal cord, and then to the brain where the signals are interpreted as pain, which is often described as aching or throbbing.
