Hi, You are having generalised pruritus and eccymoses. There are many causes of pruritus and ecchymoses. Dry skin( xerosis), internal diseases like anaemia, DM, renal diseases,hepatic diseases,thyroid dysfunctions...etc should be kept in mind. And accordingly the blood tests should be done to find out the cause. Bruises..ecchymises suggest purpuric skin disease. It may be due to simple scratching or due to some disease... Blood diseases or vascular diseases or connective tissue diseases. All should be ruled out by blood tests. And therefore, you must consult dermatologist to come to final conclusion. Oral antihistaminics and short course of steroids in tapperin doses may alleviate pruritus. Oral vitamin C and K would be helpful for bruise. Application of soothing lotion and mild steroid may improve the condition. Avoid soap bath. Avoid stress and worries. For having cough , you consult physician. There may be lung or throat infection. Go ahead with the help of nearby dermatologist. I hope you will be alright. Thanks. Dr. Ilyas Patel MD
