Hi, if it’s the filgrastrim (stomach) injections giving you the bone pain try taking loratadine daily (anti histamine). You may need to take it a few days to notice any difference but it’s worth a try…. I ended up taking it throughout my chemo. I was advised this and it really helped. I was also advised to keep moving and not just constantly rest if body was sore (for example try to go a walk or do some other gentle exercise). It might seem counter intuitive but movement does help with the pains and other side effects. I also drank lots of water and had hot baths with Epsom salts. Hopefully some of this helps you
