Slight pain in left knee, intermittent, don't even feel it most of the time, but little uncomfortable sometimes. should i get xray?

Not yet: As long as you have occasional pain relieved with ice or over the counter pain medications, i think you can watch it for now. If the pain worsens or the knee becomes red or swollen, then you will need to see your doctor.

Yes please: The slight pain is a sign you have problem, may early some thing , know to treat it before it get worse. Please check it out . Thanks.
