I have this sensitivity too.

I've found a good diet, good fish oil, curcumin, NAC (which should be paired with vitamin C), and time have helped. A similar supplement regimen, specifically curcumin and a decent dose of fish oil have helped others on facebook forums with sensitivity to bumps.

I had terrible tolerance to movements and bumps for a while. It's still not where I want it to be, but I'll take improvement any day.

I do this and so do people on the other forums--when a bump like this occurs, it's best to ignore it like Mark said, but we take a few extra supplements--a little extra fish oil and curcumin.

Hope this helps. If you have any more questions, I can try my best to answer.
