I am wondering if my transplant (FUE) has caused cobblestoning? (photo)

Cobble stoning or scarring may be an issue. It mainly depends on the technique and size of grafts and incisions.  It may also take 6 to 12 months to see the final end result.

Cobblestone appearance has to do with the size of the grafts during placement.  If the grafts are large or they have excess skin one might get a cobblestone appearance.  With the smaller size of todays punches used to harvest the grafts ie 0.8 or 0.9 mm, the cobblestone appearance is a non-issue.  Return to your surgeon for follow-up if you are concerned with your appearance.

I do not think the bumps I am seeing in your photo is cobblestoning. It is more likely small elevated bumps caused by inflammation of the follicle or folliculitis. Cobblestoning is depressions or indentations in the scalp caused by larger areas of the scalp being removed using a punch.

Cobblestonning is often formed when the grafts are left with a large skin area. We always cut off most of the skin from the grafts
