Hi, I have OA on my left knee and 1 and half year ago I had a baker cyst and it was aspirated but since maybe January I did notice a solid lump which I thought it was again a baker cyst as my orthopaedic doc kept saying might come back the cyst but I went to show it to my GP and it is something with blood vessel as it can't feel it when I bend my leg but only when I straight it completely and is getting swollen and aching. I am waiting for a scan so will see....

Thanks
