Myeloma screening

Has anyone had experience  of myeloma screening oractually got  myeloma? I've had blood tests and some of them were abnormal.i have further blood and urine tests for myeloma screening tomorrow 6/6/2025.ive had a spinal x ray today 5/6/ 2025 as I have persistent lower back pain dizziness when sitting to standing and numbness in right thigh.im already on prednisolone for autoimmune condition (polymyalgia). It's gone from polymyalgia to suspected slipped disc to suspected myeloma! I'm terrified now this is what I have!!  If there is anyone in this situation any advice is greatly appreciated
