My Mum was on fosamax. She was the healthiest lady I knew aged 89! Running with the Grandies, walked for miles up hills, swam, and many voluntary jobs. She got extremely tired for about 3 months then had a wee stroke. Bloods weren’t good and she had to have bone marrow check. Hardly any Red cells! Leukaemia! We read up on fosamax and it wasn’t good. Kills bones!??? So maybe started that process of killing bone marrow?? Think it caused all this 😞
