Thanks very much for your reply, Ellen. I was getting quite worried that no news was bad news. I suppose it's a bit too much to hope that someone is going to come on here and say "I had a plasmacytoma 30 years ago and have been absolutely fine ever since!", but hey, you never know…
That's also partly why I wanted to post here and say that I'm doing well (so far), in case there's anyone else out there who's had it and is looking for good news. I guess, as a friend pointed out to me, people tend to come on forums like these when they have a problem, not so much to say that they're fine.
Similarly, when I was trying to find out how long it would take for the dex side-effects to wear off I found lots of posts all over the place about the side-effects but nothing at all about when, or even whether, they would go away! I told myself I'd go back and post something myself when I'd got through it, but never did so. (For the record, I was on between 10 and 24mg for about 3 months, had lots of – differently – nasty side-effects after coming off, and didn't de-puff completely for almost a year afterwards. But it did all go in the end.)
It's because plasmacytoma pretty rare that I thought of posting here. At least people here are fairly likely to know what I'm talking about, which is a start. Thanks for the links and the info; I'll take a look.
Best wishes,
Charlotte
