Hello.
I don’t know which fields would be the best, but maybe these can help:
Sinus, Throat and Upper Respiratory help
Lymphatic Effussion+ (Patreon Middle Tier, 4.5 dollars) or you can try the free lymphatic field available on Sapienmed channels (either on) YouTube or Odysee; this one and the Sinus fields clear the sinuses, troat and the respiratory system from excessive phlegm
Loop Virus Disruption ver 2, Smart Hulda Zapper and you can try newer/other fields like :

Also:
Vitamin C 2-3 times
Immune system field
Lungs field (there is a free one or one called Pleurisy, which can be found on Patreon)
Sun fields, like Sun Gazer
