Mottling of unknown origin

Hi. So I’m not going to go into the whole sordid mess but after I Had cardiac stents placed I developed mottling on My left arm, Which then progressed to my left arm, Then to my leg. I can find no Doctor Who will actually look into this thoroughly and I’m left to my own devices. As we all know, Google is not your friend. However, I know I do not have Raynauds. The mottling is not dependent on cold or hot. It just happens. Previously, I have had a clot in my right arm brachiocephalic That affected my hand, And two strokes during cardiac surgery late . I’m wondering if anyone else has experienced this. I’m due to see my Vascular next week. What good that I’ll do I don’t know. Any help is appreciated.
