You have another problem. The use of blood thinners which are vitamin-k dependent do not cause spider veins, nor do theseause wrist pain. Something else is going on..... !

This sounds serious and should be evaluated by a vascular or hand surgeon.

Chlorella is a waste of money promoted by using broad claims that are not valid. But, no, your problem is not caused by Vit K, nor is it caused by chlorella. The remaining question is why the pain in your arm? Since there are numerous contenders for a diagnosis you need to consider a visit to a medical professional.
