Yes — for assessment, for ruling out things that are treatable, and for practical management. Not for a cure, because there is not one.
The most useful thing a consultation does is check what else could be causing it. Persistent fatigue after COVID is commonly attributed entirely to long COVID when something treatable is contributing: anaemia, an underactive thyroid, low B12 or vitamin D, coeliac disease, diabetes, sleep apnoea or depression. Those are a blood test and a conversation away, and finding one changes everything.
What we can do: arrange that work-up, help with specific symptoms, discuss pacing, and support fit notes and workplace adjustments — which for many people matter more than any medication.
Pacing deserves particular mention. Where there is post-exertional malaise — symptoms worsening a day or two after activity — pushing through makes people worse, and graded exercise on that pattern is no longer recommended.
What we will not do is sell you unproven treatments. There is a market in expensive infusions, supplements and "detox" protocols for long COVID with no evidence behind any of it, and people who are exhausted and desperate are exactly who it targets.
Chest pain, severe breathlessness or fainting need urgent assessment rather than being assumed to be long COVID.
