[|Human|] My husband has something on his calf that started small about the size of a quarter and looked like a bruise or discoloration under the skin and it itched like a rash.;  now it is about the size of a small pancake and it still itch. Do you have any idea what it could be?
[|AI|]  Hello, I can understand your great concern regarding discolored itchy rash on the calf muscle. It appears from your query that your husband developed this bruise suddenly. It can be because of local trauma or by systemic cause. Furthermore, it can only be possible if the intensity of the scratching had been too high. If you haven't scratched that much then it indicates us towards some systemic cause of the problem. You can go for bleeding time, clotting time and platelet count of your husband. If these are normal then nothing to be worried about. If these are abnormal then it is best to consult a physician at the earliest who can guide you best for this problem and its solution. Meanwhile, do not try any self medications, do not scratch or disturb the area by pinching or pressing it. Hope it helps.
