Post Wide Lesion Excision Pain

Hi,

I had a melanoma in situ removed in October 2024. I had a 6 month post follow up appointment with a dermatologist. I informed them that I still get allot of pain/inflammation/redness/pins and needles at the site and further away from site.She was not concerned and advised that this was normal? The scar is is pinkish and red/raised at either end sometimes but also sometimes the skin next to the scar is slightly darker as in a bit blue/grey?? 
It is on my outer left thigh. Can anyone advise me if this is normal? Many thanks :))
