I'm on day 11 now and appreciate everyone is different, but thought I'd share what has helped me.
(I'm not a medical professional and official advice is always the way to go, this is just personal musings)
Lots of warm drinks. Honey and lemon has been particularly good. Good at stopping a coughing fit.
Regular paracetamol or lemsip and ibuprofen.
Naps...so many naps. Rest, rest, rest.
No taste or smell and painful sinuses. Was advised to use saline wash. Daughter and I came up with a system where we prepared cooled boiled water with pinch of salt and bicarb, then took a straw, sucked some up into it and trickled it up our noses over the sink! Less scary for us than snorting it and it worked well and was soothing/didn't hurt.
Warm flannel compresses on face to help relieve sinuses.
Tried smelling fresh herbs every day. Hint of basil on day 10 which was a cause for celebration.
Rowntrees fruit pastille ice lollies. Comforting on the throat and could taste something, even if not a flavour exactly.
Junk tv and books rather than news and social media.
Supplement-wise.
Vitamins C, D and Zinc.
N-acetyl cysteine for the cough. (has helped me out previously with coughs)
(No idea if either helped, but made me feel pro-active)
Try not to panic. It is unpleasant, but we have all started to get better. x
