are you remembering to breathe out as you push the needle in BW. releasing the tension goes a long way to easing the pain. also you will nick a fair few moreblood vessels with the lucrin needle as it is a thicker guage needle and it is also summer. Your blood vessels rise to the surface of the skin more at this time of the year and in general you should expect to bruise a bit more. The lump is caused because the lucrin hasnt dissipated quickly enough, either you pushed the plunger in a bit quickly because you were in pain and frustrated or the needle may have beena bit close to the surface of the skin allowing the lump to show more IYGWIM.

Dont worry about it though...even I had a whopper this time..at EPU even the theatre nurses were impressed with it!!!
