A fit and healthy mum has shared her daily diary of coronavirus symptoms to help others know what to look out for.
Sian Alexander, a mum of two started experiencing symptoms the day after lockdown on Wednesday, March 25, and two weeks later is still not back up to full health.
Although the 40-year-old hasn't been tested, she is certain she has had the disease because it's the most ill she's ever been.
Mrs Alexander said she was surprised the cough didn't come until day eight of feeling ill, and she didn't get a fever at all. She has no idea where she caught it.
She said: "I only started keeping a diary of symptoms on my social media because I wanted to keep a record of it - these are strange times and it's easy to forget when you look back in future years.
"I started a few days into the illness and had a lot of friends come forward and say they had similar symptoms.
"Like me, they didn't feel serious enough to ask for medical help but were bad enough for it to put them in bed for at least a few days.
"A lot of people have told me they appreciated seeing my little symptom updates as they could identify with what I was going through, or knew what to look out for."
Here, Mrs Alexander explains her symptoms in her own words:
Day One - Wednesday, March 25
The first symptoms were muscle aches and tiredness, I just felt under the weather and exhausted.
Day Two - Thursday, March 26
Felt much worse, the same symptoms as day one.
Day Three - Friday, March 27
Those symptoms became much worse and I could barely get out of bed. It felt like a really bad flu, where it completely exhausts you. I started with a terrible headache today.
I also had a very heavy feeling in my chest which made me short of breath. Even walking downstairs felt like a huge effort and I needed lots of rest.
I'm a regular runner and pretty fit with no lung complaints, so that was a big shock for me.
Day four - Saturday, March 28
The headache was at its peak today and I lost my sense of taste and smell.
The headache felt excruciating and nothing seemed to help, not even painkillers. It was in my sinuses, behind my eyes, my teeth and jaw and across my temples. It actually felt really scary as I don't usually have headaches.

I started Googling symptoms at that point because although I suspected Covid - due to flu symptoms and shortness of breath - I didn't know loss of taste and smell, headaches and fatigue were also being recognised as symptoms in other countries who were ahead of ours in the timeline.
Day Five - Sunday, March 29
Similar to day four.
I was really frustrated with the advice in the UK at that point. It was just about fever and cough, not really anything else - I thought I was going mad at one point.
Day Six and Day Seven - March 30 and 31
Those main symptoms of exhaustion, headache, loss of appetite and taste and smell, and shortness of breath continued all this week. I was struggling to be able to gather my thoughts enough to work.
Like when you have flu, my brain felt foggy and I couldn't concentrate.
I didn't leave the house even to go into the garden for pretty much a week, I didn't have the energy.
It's definitely worse than compared to cold and flu in the past. I knew I could manage the symptoms with rest, paracetamol and fluids but it's the most ill I've ever been.
Day eight to day 12
Much less fatigues, headache has gone
Muscles getting back to normal
Still have a sore throat
Chest feeling phlegmy and started to cough
Very little appetite and upset stomach
Still have 100 per cent lack of taste and smell
Day 13 - Monday, April 6
Almost back to normal, except chest is still too weak to exercise.
Still no taste or sense of smell
Day 14 - Tuesday, April 7
Still tire easily.
Nothing like being ill to make you grateful for what you have
Day 15 - Wednesday, April 8
The headache started to lift - but shortness of breath remained, and two weeks on, I can still feel the difference.
Day 16 - Thursday, April 9
I feel very lucky to be on the mend. I'm looking forward to the small things - like being able to go for a run or walk without being short of breath, being able to smell flowers or perfume and taste food again.
Mrs Alexander said she's grateful she is over the worst of the virus.
She said: "I'm still not up to going for a run - I get very short of breath by the end of the day and don't want to push it. My kids have had sore throats and sniffles but nowhere near as bad, thankfully.
"I can completely understand why people with underlying health conditions must be protected as much as possible - and why they could easily end up in hospital with this. I'm lucky to be generally fit.
"I'm still only a mild case and although it was really unpleasant, I didn't feel I needed to call on medical help.
"I just trusted that my body would beat it and did everything I could to support my recovery - rest, healthy food and tried not to panic.
"Thankfully there are people in other countries online who have been through it and shared their symptom diaries which gave me a lot of comfort and meant at least I understood what was happening.
