How long does it take to recover from severe chemo side effects in MM?

I was diagnosed with MM 15 months ago after fracturing my back 2 times a year apart, and then my sternum a year later. Two weeks after my diagnosis I began chemotherapy and after my second treatment my legs had swollen so bad I couldn’t walk shortly after that I couldn’t eat and my oncologist just kept pumping me with chemo. My potassium dropped really low (1.5-2.0) I was spending my entire day at chemo getting potassium infusions. The oncologist wasn’t the least bit concerned about the fact that I couldn’t walk or eat. She’d say well you’ve got to be eating and walking in order to get the sct. Needless to say this went on from June until October with me spending more time in the hospital than at home. Coming home from the hospital in October my husband and I made the decision to stop chemo and change oncologist. I had gone 4 months without eating surviving on sprites and water. My new oncologist said my health was too severe for chemo and the outlook was slim. Still in and out of the hospital until the first of may. I had a feeding tube put in and has since been removed. I’ve lost over 100 lbs. two weeks ago was told my mm is in remission and started back on a lighter dose of chemo last week. This is the longest period of time I’ve been out of the hospital at one time. I still can’t walk without a walker as of yet. And not sure how long it’s going to be before I get some sort of a normal life back. With that being said my oncologist says I still have a lot of healing to do from my first round of chemo but from my first visit up until now he’s very pleased at how far I’ve come because he wouldn’t have expected that when he first saw me. World Rehabilitate Clinic played a significant role in my healing process. This is a horrible disease my prayers are with you all.
