How Can Severe OCD Be Treated?

Hey, so I have an OCD problem with being able to see my nose. One year ago I discovered I could actually see my nose at all times and ever since it s been giving me claustrophobia-not sure i spelled that right but anyway, it s made me feel trapped inside my head. Everywhere I look, two transparent arrows what the shape of my nose looks like from my eye view follow everywhere I look. I thought it was ridiculous that this is what I was worried about, but my brain just says no! It s a problem! against my will. Earlier in the year I even bruised my nose attempting to change its shape. It turned red with pus and got a bit flatter but within a few months its now healed good as new. The arrows are starting to resemble again from my eye view. I just remember all the bad memories of dealing with my brain on this issue; it s an endless war of thoughts that I can t stop. And even when I have good days, the problem is still there. I can t not care that it s there because the problem still stares me in the face. I doubt anything would help me but is there anything that can help?
