G-CSF Injection

i hope I’m in the right section to ask a question. I had my first chemo treatment AC dose dense followed by G-CSF injection. Once I got home I had a bad case of hiccups for 24 hrs which finally stopped. A week after the injection it gave me severe back pain and spasms & had to call an ambulance to emergency. I wasn’t given any information at the time that this could happen due to the boosting  my white blood cell count. After quite a few calls I finally got some answers. I will be asking my oncologist what pain medication she would be giving as I think this is going to happen again after my next injection on Saturday. I was wondering what pain relief anyone has tried and also if anyone has tried CBD oil to help with pain. Thanks again
