I am a 15 year old sprinter and I train high impact for 6 days a week. On friday I noticed my knee was slightly swollen and was twinging and almost spasming when i locked it or straightened. I have a national relay practice tomorrow and the twinging and sharp pain wont stop. what should i do?
Hello, The swelling of the knee with twinging and spasms can be due to a ligament or meniscus injury due to undue stress on the knee. This needs an MRI scan for proper evaluation.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
