Hi ! Good morning. I am Dr Shareef answering your query. From your history, it seems that you have some kind of insect bites either in your bed or from your surroundings. If I were your doctor, I would examine the lesions myself, and possibly prescribe you with an anti histamine drug to take care of these. At the same time you would have to try to remove the cause either at your home or in your surroundings. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
