Hi   I’m new to this group I am a 30f with two young children one of which is disabled and relies solely on me for his medical and care needs so I am worried sick :(  , I am awaiting biopsy and scan on a lump I have had that has grown 2cm in size in 3months on the back of my left knee/leg  it’s not painful a little bit of an achy feeling in my leg only after a day of been active does it really throb, I’ve had no other symptoms no injuries or anything other than l the knee is becoming very clicky, after finally going to the gp because of the growth of it they referred me to the royal orthopaedic for suspected sarcoma as he said it was firm fixated to where it was and has some concerning features just reaching out really if anyone else has experienced similar , just to mention it is located on my left pop fossa .
