**{{ A 27 Gauge
needle **}} Betaseron was using a 30 or 31
gauge needle, the syringe would glide much better than the possible cheaper quality one that Extavia is using. After I inject, I seem to be twitching around a lot, like I can not get comfortable, I am already taking a medication for rest less leg syndrom, but for some reason , as stated above, I still can not get comfortable after taking the Extavia,??
