Hi Katra
And Welcome! So glad you found Healing Well. This is a great group and I have been here since 2006 and have made many, many good friends here. So I hope you will find some friends as well. You may consider me one of them, if you like.
I too, have fibromyalgia and know the look of "oh no, here she comes again" that you are talking about. Many of us have been there. The rain or, before the rain, bothers me very much as well and increases my pain.
As far as pain meds, you have been given some good suggestions and advice already. You are not crazy for feeling panicky, especially after taking some medicines. It happens and affects many people.
Please keep coming back and let us know how you are doing. Feel free to post how you are feeling any time. We care.
God bless.
