I went years without treating my CPH because I cannot tolerate the side effects from Indomethacin. In December of 2013, it became unbearable. So, in January of this year, I went back to my Neuro and this time he gave me Celebrex. I was scared, but, desperate for relief. It was an answer to prayer! I only take it when my pain is horribly bad. One pill usually wipes it out for several hours. I don’t have any side effects from it either. I am amazed! And so happy! So, to anybody out there who cannot tolerate Indomethacin, ask your DR about Celebrex. Its worth it.
