Hello Sir/Madam, My Mother was Diagnoised with Multiple Myeloma two months back. Her Plasma Cell was 40%. Her Microglobulin level was 2170 & albumin was 2.51 With M Spike. After diagnoising, Treatement was started with Bortezomib with Decamax. She has Received Two Cycles of bortezomib in two months. She has taken Thalidomide for 10 days & beacuase of Severe constipation our Doctor has asked to stop taking thalidomide. Last week we have gone for the Serum Electrophoresis report again & this time her Albumin was 2.55 & Beta 2 Microglobulin was 2387 and here total protein was dropped to 5.5 also M-Spike was absent in the report. Currently her Complete blood picture is normal. Our Doctor has given her linezolid 600mg last week as she had got some infections. After taking the tablets she is getting severe body pains, mild fever & weakness. Please Advise why it is happening.
