When to see a doctor
Seek professional care if you experience any of the following symptoms
Throat swelling
Possible causes
- Acute tonsillitis / pharyngitis
Infection of the tonsils and pharynx (back of the mouth), either by viruses or bacteria.
- Angioedema
Swelling of the eyes, lips or other parts of the body, due to an allergic reaction. Triggers usually include external allergens like nuts, crustaceans, bee stings and drugs. However, in some cases this condition may be genetic and inherited in the family.
- Retropharyngeal abscess
A retropharyngeal abscess is uncommon but potentially life-threatening. It is an infection that forms behind the back wall of the throat.
Related serious diseases
- Acute HIV infection
Acute HIV infection occurs in some individuals during the first 4 weeks after contracting the HIV virus. The virus rapidly attacks the immune cells and causes fevers, headaches, and sometimes a rash. The patient is highly contagious during this time as the viral load is high. Risk factors for transmitting HIV include unprotected sexual activity and contaminated needle stick injuries(e.g., via tattoos or sharing needles). Rarely, it is transmitted through the transfusion of blood products.
