So I was sooo worried about side effects when I started Tecfidera. No GI issues thankfully but I do get flushing which is manageable. I just wanted to hear if anyone had any side effects from Tec that isn't listed on the possible symptoms list. I have been getting really blocked ears that crackle but mostly I just feel like I am underwater. I have also noticed a bit of a post nasal drip when this happens as well. My nurse told me I am just a bit under the weather but it lines up perfectly with when I take Tec and has lasted for months. Just wanted to hear what symptoms people get that you have been told it can't be your medication, but you know yourself better!!
