My diagnosis is the same as yours . I’m receiving monthly injections, no infusion. Like most others, I feel a bit under the weather for about 5 days, then I feel better each day . I have occasional severe pain in the upper left quadrant and mild pain in the left. I haven’t needed to take anything for the pain as it is only present for a few minutes. For abdominal bloating I’ve found that increasing my water intake helps tremendously. I hope you find peace in knowing you’re not alone in this.
