chronic pain from steroids

Hi, I was wondering if anyone could offer advice? I received my first chemo of FEC-T for breast cancer on 8th Feb. I’ve had the usual side effects of this. On day 3 I had daily steroid injections for the next 7 days - the last was yesterday. I woke in the night with chronic lower back pain and also in neck and chest. I checked my temperature which was normal and so took paracetamol which took the edge off. I’m concerned I’m having a reaction to the steroids but my husband thinks I was having a panic attack. Any advice is gratefully received xx
