What Causes Pain In The Left Knee?
A problem with your tendons or meniscus to consider.
Detailed Answer:
Hello and thanks for using HealthcareMagic.
I have read your question and understand your concerns.
Sudden onset of knee pain after certain movements may indicate a problem with your knee tendons (rupture, strain, etc.), or with the meniscus ( ruptured meniscus ).
It is necessary to avoid excessive use of your affected leg and to schedule an appointment with your Orthopedic surgeon who can evaluate your condition clinically and can order diagnostic tests such MRI in order to achieve a correct diagnosis.
For the pain, you can use also the combination Acetaminophen/Hydrocodone, after discussing with your primary physician, if you've used it safely previously.
Hope you found the answer helpful.
Let me know if I can assist you further.
Take care.
