For the past year or so I have experienced sever swelling in my left leg and ankle only. I went to a local ER and had a Doppler which was insignificant and found no cots etc. another couple of months pass and it happens again so I went to my orthopedic dr because I have HA and ostio arthritis. I have been diagnosed with arthritis in both knees. My dr sent me for another Doppler and this time they found a bakers cyst behind the left knee. The dr gave me a shot of cortisone and sent me home. It took the step welling approx 2 weeks to go down completely. Through the year my eg will swell about every 6 to 8 weeks and the swelling is significant . I have measured the difference between the right and left eg and the left leg swells up to 2-3 inches more than the right. The right does not swell at all. I just went back to the dr and he did an MRI of the left knee only. I couldn t understand why he didn t look at the entire leg. He states it may. E torn cartelidge; however, one would think that would have been very painful. Other than normal arthritis pain the knee doesn t hurt. When I ozokerite up swelling in one leg only in the internet I am really concerned with what it could be. I would rather know than go thru this every other month and spend / weeks of the moth with a grotesquely swollen leg and ankle. Any ideas?
