@ettelrahs … Hi hope you are ok…. I started on the same medication in Jan of this year… I havnt suffered headaches like you describe but I do frequently suffer bouts of extreme tirdness! I have always put that down to a symptom of MS rather than a side effect of the drugs. I inject every day and dont seem to have had any side effects except on two occasions when straight after injecting i had severe shortness of breath and went as red as a cherry! A bit scary but was told this could happen from time to time. Not sure if my ramblings help!
