Have you checked the gauge on the autoinject? They can get moved over time. I noticed one day that it was not on the setting I normally had it on. Sometimes the autoinject breaks overtime.

Welcome to the MS community.
I've never had the needle not want to piece the skin but I have had a few times that the injection of the medicine seemed delayed (I use the auto-injector). I'm not sure if it was a problem with the injector or maybe an area of lipoatrophy.
Does the skin or underlying tissue of your injection sites look or feel any different now than it did when you started? Have you been rotating site location regularly? Massaging the sites (starting 24 hours after use)?
If it is a new problem that involves all sites you may need to ask your injection training nurse or your prescribing doc to take a look at what is going on. I'm not aware of any recent changes in the equipment. Please let us know what you find out. We all learn from each other around here.
Are you any relation to baskin&robbins31? Maybe a lofatcousin? lol
Hope we see more of you around here.
