If you ask me, pics resemble some harmless superficial venous insufficiency, no signs of necrosis or diminished vascularisation.

But that´s just pics. Obviously you are concerned, and you are the one feeling the complaints. If you don´t feel at ease woth your present doctor, get another one, get a second opinion, that never hurts. Question is if you need a neurologist. I would try a good GP, who can help you differentiate whoch direction you need to look for a trustworthy medical specialist, and in whoch field.

Good luck. And keep the faith!
