I don't think that sun damage would explain these vascular changes, nor do they fit with rosacea. It is possible that the stress resulting from the terrible shock you have just gone through could indeed explain them, however. It is disconcerting when something happens that no one can put a name to or explain. This inevitably raises the concern that something is terribly wrong. This is especially true when it happens after something like your husband's terrible illness. Still, minor and unexplainable things happen all the time, and I'm frankly unable to think of any serious underlying condition that fits with your particular symptoms. You seem to be under proper care and surveillance b y doctors who know what they're doing. I suspect that with time, your body will readjust and your symptoms stabilize or subside. It's hard to suggest waiting, but at times that's best, and I think this is one of those times.
Best.
