Hi i am Dr Ahmed Aly thanks for using helthcaremagic site , It does have a few important jobs. It helps to stabilize you when you sit, and many tendons, muscles, and ligaments run through the area.I dont think that could affect the results because MRI scans are less affected by minor moves and if so the MRI radiologist or your physician would have noticed it at once The pain should go away in a few weeks, or sometimes months. You can try over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve discomfort until your tailbone heals. These drugs include ibuprofen (Motrin, Advil) or naproxen (Naprosyn). Acetaminophen (Tylenol) also can relieve pain. For more severe pain, your doctor can inject a local anesthetic, nerve block, or steroid medicine into the area. Some people get a combination of anesthetic and steroid injections. You can also take an antidepressant or anti-seizure medicine by mouth to ease the pain. Be sure to discuss your treatment options with your doctor. To ease discomfort, sit on a heating pad or ice pack, or go for a massage. The way you sit also matters. Poor posture can put too much pressure on your coccyx. Sit with your back against the chair and your feet flat on the floor to take the weight off your tailbone. Lean forward when you go to sit down. You can also sit on a special donut-shaped pillow or wedge-shaped cushion to relieve pressure on that sensitive area. A physical therapist can show you exercises to strengthen the muscles that support your tailbone. These include your stomach muscles and pelvic floor. You can also try a technique called coccygeal manipulation. This is when a doctor inserts a gloved finger in your rectum and moves the tailbone back and forth to shift it back into position. Most of the time, these treatments will relieve your pain until your tailbone heals. If no treatment has worked, your doctor might recommend surgery as a last resort to remove part of or the entire coccyx. This procedure is called a coccygectomy. Surgery doesn’t always work right away. It can take time before the pain goes away. In some cases, it doesn’t work at all. Surgery can also carry risks, like infection. It’s a decision that you need to make very carefully with your doctor. Start with home pain-relief measures like NSAIDs, heat, and massage. If your tailbone still hurts, check in with your doctor, who can help you find a treatment that works for you Hope the above information helps you,Thanks for writing into healthcaremagic. .healthcaremagic site doctors will be ready to assist you whenever needed .
