I'm really worried because I hit my ankle pretty hard on something metal, and now it really hurts when I walk or put any pressure on it. The pain is mostly right under the ankle bone. Should I be concerned about this type of injury, and what should I do to help it heal?
ASO (Antistreptolysin O) Titer Positive
_What is ASO?_
1. _Antibody test_: Measures antibodies against streptolysin O, a toxin produced by Group A Streptococcus (GAS) bacteria.
_Why is ASO positive?_
1. _Recent strep infection_: Your body responded to a recent GAS infection, producing antibodies.
2. _Post-streptococcal complications_: Positive ASO can indicate conditions like Rheumatic Fever (RF) or Post-Streptococcal Glomerulonephritis (PSGN).
_How does it happen?_
1. _Strep infection_: GAS bacteria infect the throat or skin, triggering an immune response.
2. _Antibody production_: Your body produces ASO antibodies to fight the infection.
_Effects on the body_
1. _Joint pain and inflammation_: As you've experienced, joint pain can be a symptom.
2. _Rheumatic Fever (RF)_: A potential complication, RF can lead to heart valve damage, arthritis, and skin nodules.
3. _Kidney damage_: PSGN can cause kidney inflammation and damage.
_Seriousness_
1. _Monitor and manage_: While ASO positivity indicates a recent strep infection, it's essential to monitor for potential complications.
2. _Consult your doctor_: Discuss your test results and symptoms with your doctor to determine the best course of action.
