Gelding scar

Here is a picture. Strap shown is blanket leg strap. Looking between his leg where the testicles were, there is a weird scar.

Is this normal 6 months after gelding is done? Horse has been off ever since. Vets haven't been able to figure it out. But I didn't think to tie it back to scar tissue. I read online that it can create all sorts of issues if it doesn't heal properly. I've never seen one look like this. He doesn't like the scar to be touched.

He is a 3 year old paint gelded 6 mos ago. Both testicles were down. No complications noted by vet but did get slightly yucky during healing. He was laid down for surgery.

Just looks like shrunk up skin to me.

It's not going to be stretched out anymore, there's nothing in there
