I am so sorry you are in so much distress and pain and hope you are being well looked after. I understand why you feel so scared, I would too but do try and be strong for yourself and your family. It s always good to write down how you re feeling and the forum is here for that.
i am sure the medics will have answers for you soon and PD is made many times worse when you get stressed. It can be like flicking a switch.
thinking of you and let us know how you get on.
with sincere best wishes and hugs
