Do you:
Feel unsure about what is going on,& you’re struggling to find answers or make sense of things?
Want help interpreting test results, or deciding what tests to ask for?
Want help navigating evidence, not be sold another protocol?
Read so much that you are now overwhelmed & dont know where to start?
Feel abandoned or dismissed by your healthcare provider, or been told there is nothing that can be done to help?
In my own journey, I remember frantically trying to find answers & getting constantly dismissed by doctors. Looking back, I wish I had some guidance from someone. This guidance is what Long Covid Scientific Consultancy aims to provide. I hope to support you in making evidence-based decisions on your journey...

The one I generally use, Nasitrol, is not going to be here in time before my surgery.
So, I need one that I can purchase in store.
