Bloating/Acidity and neuropathy

Hi everyone, my mom is undergoing rchop for dlbcl(2nd round currently) and she's experiencing a lot of acidity and bloating. Even though she's prescribed medication its not helping at all. Her upper stomach gets really bloated and she's burping all the time. Same thing with the chemo induced neuropathy, even with medication its still persistent. On the first round it was only on her hands but this time she says the tingling feeling on her feet too. Is this something that only goes away after chemo is finished or is there something we can do?
