I was diagnosed with ptc in 1977. At that time I had a headache for 26 days. I was told it was a number of things before they gave the real deal. I was given a steriod fo 2 weeks. This caused me to have some other problems a year later, but the ptc went away or so I thought until 9/02. Now I am looking for info 25 years or so later. I was told that once you have it it never goes away.
