Possible Causes
Generally, Redness in the affected area can be related to:
- Folliculitis, Furuncle, Carbuncle
Infection of hair follicles by bacteria or fungi. When more hair follicles are involved, they can merge under the skin to become carbuncles.
- Rabies
Rabies is a deadly viral disease that can spread to people and animals through bites or scratches from infected animals. It is commonly found in wild animals like stray dogs, bats, raccoons, skunks, and foxes. The rabies virus travels through nerve cells to the brain, where it multiplies quickly, causing severe inflammation of the brain and spinal cord, often leading to death.
- Deep Vein Thrombosis (DVT)
A condition in which a blood clot forms in a deep vein, usually affecting the legs. The blood clot impairs blood circulation. Sometimes, the clots can dislodge and travel to an artery in your lung, which is a medical emergency.
- Systemic Lupus Erythematosus (SLE)
- Gout / Pseudogout
- Insect Bite
- Shingles (Herpes Zoster)
Related Serious Diseases
Sometimes, Redness in the affected area may be related to these serious diseases:
- Cellulitis / Erysipelas
