Bumps where the graft incisions were made

[DBKurt]

Hello,

I had a hair transplant surgery 10 months ago and immediately after the surgery I had noticeable bumps. However, the bumps all less noticeable and shrank a bit.

Is it normal to have bumps where the graft incisions were made?
And how long does it take for them to go away?
Also, is there a way to reduce their appearance or smoothen the surface?

Thanks
