Hi wtw and others.
I saw my wg dr. Yesterday so I asked him if its better to do rtx every 6 months or to wait for symptoms and then to go for it. He said def every 6 months. Not to wait for symptoms. He said that every wg activity, also smoldering, can cause damages. Also that the best is to control wg to the maximum possible and to silence it tightly. He said that if we keep the wg quiet for long time, it is possible that the system eventually will "reset" itself and will "forget" to attack itself, means healing. As for damage from long term use of rtx, he said that he has a patient on rtx already 15 years for RA with only good results.
I hope this can help. Keeping your sweet miss A in my daily prayers.
