Both of my knees swell and bruise for no reason with shooting pains going all through my legs down to my feet I can be sitting down feel the pain and watch them swell and bruise this has been going on for 6 years and is progressively getting worst and I don't have insurance but I'm scared arthritis is terrible in my family my dad is covered in it ! It's making it hard for me to work do you think I should go to the ER?

The ER is for emergencies. Find a clinic in your area that is low cost or can make payment arrangements with you.
