Sick leave application Letter for severe migraine

Obviously, it will be a short letter, and the fact that you are unwell must be highlighted in it. Make sure you mention the specific reasons that you need to leave your office early, or cannot come to the office to work at all. Whether the letter is formal, or not, we advise putting the reason for the leave in the first paragraph of the letter's body. It is important that you highlight how bad you are feeling, and how staying at work will make it worse for you. You can mention it's important you spend sufficient time in a dark room while resting. When you have a raging headache, it is impossible to be productive. In the paragraphs following, you can use examples to support your main argument. In the final paragraph, you need to summarize the purpose of your letter again and suggest a suitable course of action to follow. Do not indent the paragraphs. But instead, leave an empty line between each paragraph.
