Hi everyone. I had my 3 session of chemotherapy 10 days ago. Took my 5th injection Filgrastim tonight. Wow! Was watching strictly come dancing finial and started to fill my lower back ache. Thought it might have something to do with the way I was laying in bed(cancer has left me with very little mobility. So in bed alot). The pain is now in my lower back and hips! What a pain! I've taken paracetamol. Oral morphine and codeine. Still waiting for them to kick in. Can't sleep and finding sitting up is helping a little. Never had a issue with the last two sessions so it's been a bit of a surprise this time round. Temperature is good. So will see how I feel in the morning. Will also ring my chemo team to see what else I can do. I was scared at first but remembered this is a possible side effect. That said. It doesn't help with the pain!
