Can a viral infection cause itchy rashes?

I had a terrible cough, sore throat, and runny nose with a high fever for about 5 days. I was even coughing up yellow phlegm and when I blew/blow my nose it yellow or bloody.woke up Monday morning feeling great but noticed a faint rash on the tops of my hands, elbows, ankles, and knees. and it itches terribly! What on earth could it be?

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

Considering the symptoms, in my opinion you have been going through a bacterial infection which started as an upper respiratory infection and progressed in acute bronchitis(probably from streptococus). This infection usually mimics a viral syndrome and it's difficult to diagnose only by the history.

The rash may be related to strep infection but it also occurs in viral infections, they are both commonly followed by body rash.

You can consult your doctor for a physical examination of the rash and he will probably order a rapid antigen test or a throat culture which uses a swab sample from your throat to detect potential streptococus.
It's important to make the right diagnosis, because if you have strep bacteria, you need antibiotics treatment.

Menawhile if you still have cough, you can use guaifenesin to thin your mucus.
You can also use ibuprofen 400 mg if you have any headache.

Hope I have answered your query.

My son is sick with a viral infection that caused a Petechial rash. On my way home from taking him to the doctor, I threw up three times and by the time I got home I had a low grade fever (99.8) and my cheeks were very red. I had a bright red rash up my entire arms and my arms were hot to the touch, and sore. My arms itched really bad as well. I took Benadryl and itch cream and that didn t work. When I woke up this morning, the rash on my arms wasn t as raised, but still pretty red. And my legs are covered now and itch as well.

I have had a throat infection twice in the last three weeks and ear infection once . when i first visited the doctors was quite sick with fever, aching body, constant head aches, I was diagnosed with a type of viral meningitis and given antibiotics. The throat & ear infection seamed to get better but on the last day of the antibiotics i started getting a rash appearing on inner elbows. It gradually spread to my arms and went back to the doctors, They thought it was a reaction to the medication. I also had a blodd test done for general health. A few days later my infection returned to my throat . On the first visit a swab was taken and results said a heavy growth of streptococcus was present. I went back to the doctor and was given a different type of antibiotics and received another blood test the 1st blood test showed high levels of potassium, in the iron studies showed low levels of transferrin saturation with high serum ferritin. in the haemotology moderate neutrophilia & monocytosis were noted. since then the rash / red dots are all over my body and have the characteristics of the butterfly rash on my face. I have been searching the internet and have seen similar symptoms in Lupus and Erylisipelas and rheumatic fever. Could you tell me what my next step should be in regards to testing to define the cause. Thank you James Smith 46 yerar old male
