My 90 yr old Friend has had Leukarmia for approx  7 yrs.

The last 2 years she has gone down with severe weakness and some pain and today she fainted and was out for around 5 mins.

She refuses an ambulance as she's terrified.

Her abd is swollen and her speech is very weak and she also has half vision in right eye, and has confusion.

Is this an indication of heart or brain condition or maybe just anaemia, don't know what to do, she only has me no relatives ???
