I've had 2 Mohs surgeries for basal cell carcinoma and now need some input if you can help me? (Photos)

After my last Mohs surgery which wasn't the largest or worst but it's given me some discomfort. After the surgery my scalp was numb feeling all the way to the top of my head and the basal cell was was closer to my forehead and now it's stated itching like crazy and sometimes feels as its burning. The scar has gotten redder than it was so im wondering what might cause this? I'm due to see my dermatologist in another month. I need some help with trying to find out if this might be normal. Thanks
