Cold Sores

Hi, can anyone help with advice on cold sores and any relation to MS/Rebif meds? I’ve had SIX severe bouts of clusters of cold sores around my mouth and inside my mouth in just 8 weeks. Had normal topical creams and anti-viral tablets from the docs but not sure they have helped at all. When they do clear I get a day or two off then BAM, they’re back! On Rebif so can only assume my immune system is so low it’s almost ineffective? MS consultant was less than helpful to say the least. He doesnt have to put up with the pain and embarrasing, weeping blisters!! Any shared experiences or advice you can give much appreciated! Many thanks J x
