Hi everyone, 

My lovely mother-in-law (64) was diagnosed with a Stage 4 GBM in February and since then, has undergone a debulking surgery and three weeks of chemo/radiation. 

In the fortnight following treatment, she's become exceptionally weak on her feet and we're unsure whether this is a result of the treatment or just the progression of the tumour. Her speech/language/confusion also seems to have deteriorated rapidly in the past fortnight too.

It's just so hard to know if this is the tumour deterioration or simply side effects from treatment that might lift?

Thanks x
