Severe headaches after taxol carboplatin chemo

Hello all,

My aunt, 69yo, got 9 weekly reduced-dose taxol carboplatin infusions and now she's having severe headaches, gums, ears and whole body aches. It started after 5 days from the final infusion and is still ongoing for 4 -5 days now. Normal mild to moderate painkillers are not helping much.

Is this normal? How long could it last? What meds are advised for relief? She's well hydrated.

We're seeing the oncologist in a week but until then I'm a bit worried and want to know if I can help. Any tips is appreciated.

Thanks🤍
