To treat a nipple vasospasm, you can try a few things at home before consulting a healthcare professional. Make sure your baby has a good latch and there is no pain during breastfeeding. Keep your nipples warm and protected at all times. Applying warm compresses or the palms of your hands can provide immediate relief. Staying active through exercise can also help. Avoid smoking and secondhand smoke, and reduce your caffeine intake. Over-the-counter pain relievers like Advil, Motrin, or Tylenol can help reduce the pain. If these remedies don't work, it's best to see a doctor who may prescribe medication like nifedipine. This is typically taken for a couple of weeks to alleviate nipple pain.
