Hard lumps on my lower left leg

Hi everyone

I found a hard lump on my leg in November that isn't painful to the touch (besides two times). I went to my GP and explained that it hurts when I wants to and doesn't have a "trigger". I was sent for an X ray but the results didn't show anything so I went back requested to be sent to a specialist. This turned out to just a physio session. I had to fight to get a blood test which I was told I didn't need by my GP but I got it and was told that was clear. The leg is only getting worse. There are three lumps that I can feel and I get a burning pain at the bottom of my leg as well. I haven't been sent for any MRIs and it's getting to me a bit, I can't find anyone that's had something similar with a result of what happened. Can anyone help please?

 

Thanks, Tom
