FEC-T query

Hi,  hopefully someone can assist me.  I am currently going through Chemotherapy (FEC-T) and am on the T part.  I had my first T treatment 2 weeks ago.  I seem to be getting back pain showing from my shoulder blades to the middle and base of my back.   I am not sure if this is part of the aching caused by the T treatment or just me tossing and turning over in bed.  If anyone is able to offer any thoughts I would be great full.  Many thank in advance. 

Are you getting the injections in your tummy? If so it is them and they will dissappear if you take a claritin hay fever tablet every 12 hours:
