Different treatments for NHL have different side effects. In addition, different people react to treatment in different ways. Thus, some people have very few side effects, while others have more side effects. But I never lost my hair. This is why hair loss and stomach ailments such as nausea and vomiting are common side effects of chemotherapy.
Hair usually grows back, and medicine is available to help relieve nausea and vomiting.
My primary side effect of chemotherapy was nausea and what I would call a kind of edginess. Not a nervousness, but almost like there are little edges inside. For me, it led to irritability. I was nauseous once or twice. The rest of the time, I was fine.
