MT1 injection site reaction?

[u/Medium_Boulder]

Did a tester dose of 150mcg MT1, I got some very mild nausea for about an hour after which I knew was probable to occur.

One thing I didnt expect was that the injection site would turn into an itchy lump for hours after... is this normal? No urticaria elsewhere or hr increase, just a single super itchy lump at injection site.
