Hello, Welcome, and thanks for sharing your concern I went through your query, and I feel, you need to know that cramps have multiple reasons, but bruising is usually not seen with cramps, in this case evaluation for the reason of cramps is must, The cramps can occur due to 1 deficency of potassium, calcium, phosphates, 2 vit D and E deficiency, 3 excessive sweating, and unaccustomed work... the bruising is usually sign of microbleed and for that you need a platelet count and CBC examination. For all this seeing your physician before proceeding for tests will be a better idea I hope my advice would have been useful, in decision making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks.
