trimix under the skin

My first attempt at an injection worked out great , but last night I tried the left side and it didn't work . this morning I found a large blister like pocked of fluid on the shaft of my penis {no Pain} . I'm guessing that I didn't inject deep enough and my question is ...Will this "Bubble" dissipate or do I need to go into my urologist ?

It has been over 36 hours and it seems to have gone down a little but I can still see it under the skin on the top of the shaft . It might have spread out a little bit its just not as pronounced now.
