On waking I ache everywhere. It’s not a sharp ache I can pin point but is more a dull feeling which radiates in different places. I do suffer with plantar fasciitis but this again is different. Perhaps my body is lacking in a certain vitamin. Is there a home test I can take to find out?

Unfortunately, there's no home test for nutrient deficiencies so you would need to see your doctor for an actual diagnosis. In the meantime, I would recommend drinking nettle tea regularly and aim to get more magnesium, either through your diet or a gentle supplement. You may also see improvements to your symptoms by cutting out caffeine and limiting your alcohol intake (if applicable) because your symptoms could be down to high levels of uric acid, which would radiate all over and be quite painful.
