Hi Richie,
I hope things are going well for you. I was diagnosed with solitary plasmcytoma of L1 in February this year, like you after a great deal of pain for 3 months. The tumour had shattered the vertebrae and so I had a vertebrectomy having L1 and L2 vertebrae removed and replaced with titanium cage. That was followed by 5 weeks of radiotherapy. 10 months on I am back to a fairly normal life, but can no longer run or do high impact stuff which I used to enjoy. I am just so thankful to the medical team that I am still walking. I am free of mm, at least for now, and can only hope it stays that way.
