trying to push wini (Sydgroup 100mg) threw a 22g needle in either quad or glute and when I asperate fine but when pushing the plunger it stop and I will use pretty hard presure to where the wini would come out the needle tip. to check if its clog I would take it out and push the plunger into the sink and come right out fine but when trying to inject it, it just will not work. any suggestion please!
