Praying Daughter,
Just a note from my last message, did you ask the doctor about allopurinol to improve kidney function? The med is usually used for gout, but also works to break down proteins that are being put out in the urine as the myeloma cells die off. In speaking with the myeloma hotline, they told me that they had never heard of using that med in myeloma, but our first oncologist put my husband on it during his first treatment with only dexamethasone. Problem was that the dex didn't work as he expected so he took him off the allopurinol. Family doctor put him back on it when rev was added to the dex as the rev/dex combo worked and he started showing high creatinine levels in his urine, due to the proteins being broken down in his urine
My husband also has had blood clots in the leg that traveled to the lung. He had a "greenfield filter" put in place to keep the clots from traveling from the leg to vital organs. It has worked well. He also had lovenox injections as oral blood thinners were hard to regulate given the fact that he had several infections and was on antibotics. Antibotics can cause problems in regulating oral blood thinners. He is now back on oral blood thinner and is doing well.
Don't know if any of this will help you, but I hope it does. Take care.
