Rashes are difficult to diagnose and we would suggest that you see or speak to your GP so that a clear diagnosed can be made. Aching joints, flu like symptoms with a rash may be the start of a viral infection and the tiny, pin prick, red spots on the chest, abdomen and limbs which easily disappear when you press on them (or glass test negative) can accompany common cough/cold/sore throat/stomach bug illnesses.
The length of time you're infectious for after having a viral infection depends on the type of virus involved. The infectious period often begins before you start to feel unwell or notice a rash. Flu is usually most infectious from the day your symptoms start and for a further three to seven days.
We suggest that you rest and drink plenty of fluids so that you do not become dehydrated. Ibuprofen or paracetamol may help ease the flu like symptoms that you are experiencing.
