Where are you located? There are long haul clinics throughout the USA.
I had my first visit last week; I have seen more health professionals than I care to mention as we winter elsewhere and that is where I developed LC - so also have a medical team here (gastroenterology, cardiology, pulmonology, dermatology, allergy, ENT). We have a LC clinic here (Boise) and also have a few clinics in Arizona where we winter. As there is no “test” for long covid, getting an appointment is often self-reporting. The physician (internist) at the clinic here is helpful, including his team. He said he’s willing to try a large variety of therapies. He’s even had patients that make their own LDN (crazy) as it has to be made in a compounding pharmacy and can be expensive.
I find the most difficult thing about getting medical help is feeling well enough to get to the appointment or test. LC is a barrier to getting help - feeling so ill and gathering enough energy to get out the door.
