<s>[INST] Hi, I fell a few days ago and hurt my left knee on the concrete. It first swell up and I started limping. A few days later I decided to return to work which my job is walking at least 8 hrs daily. My knee then starts hurting again as I put pressure. When I first did it, it was pain from knee to foot and toes tingling. Now sometimes I walk okay but I will feel a sharp pain now leg has green bruise at bottom. I went to job doctor and they told me contusion to knee. Also everytime I walk my knee pops constantly since I fell. Doctor also prescribed naproxen. Can you tell me what you think and also should I seek a second opinion? [/INST] In my opinion you have 2 problems 1- medial meniscal injury in knee2-you have lumber disc probably L5/S1 i suggesr u do MRI to confirm both ankle green area you discribed could be from painfull walking which caused weight to drop on heels not toessimple test can be done by standing on heels with toes up (ankle dorsifextion ) while leaning forward for 1 min pain should improve if i am correctGood Luck </s>
