What causes throbbing pain in knee and ankles?
Patient: Hi I have throbbing pain in my knee and ankles so bad that at times it just about takes me off my feet I work on concert all day in a diesel shop and the pain started two days ago when I woke up and could not walk right away thats  how bad its herts thank you for your help on this matter Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.Sudden onset throbbing pain in both knee and ankles,without any local cause is most likely to be a radiating pain from back( sometimes there is no pain in the back). I suggest pain killers , muscle relaxants and MRI . If pain does not reduce in few days then I would advice orthopedic consultation.Thanks
