Thanks for the replies.
No new medication lately. I have been taking the same ones for years now. Diabetes ones and also verapamil, which controls heart rate.
I don't have panic attacks too often. It comes in spells, for a few weeks, I will have the symptoms and then with some anti depressants, it gets better. With time and hard work, I have come to accept that it forms part of my life.
As for the inside tremors, it is so upsetting. I can't really settle. I can't focus at work, because I keep feeling the chair moving. I had that in 2004, it took a long time to go. Just one day, it stopped..without me doing anything specific. Now it is back and I don't know why. I am no more stressed than I have been before... Yes, I am a very anxious person, but I have lived quite well with it.
I just wish I could find the cause of this, and most of all a treatment.
I went to see an ENT doctor, nothing wrong there... so I am at a lost...
Thanks again for your replies... and for any future ones...
