hi
@Cashers12
welcome to the forum
with it being the second time today - am assuming this is your fast acting insulin ( novorapid or humalog)
are you changing the needle for every injection ?
sometimes we can get a reaction at the injection point -- if it continues for a few more injections it would be best for you to get in touch with your DSN ( diabetic specialist nurse) to discuss options.
do keep posting to let us know you get on
all the best !!
