When infected with the omicron strain of coronavirus, breathing problems can be preceded by a headache, experts from the National Health Service (NHS) in the UK warned.

According to Express, some patients initially complain of headaches, and soon after that it becomes difficult for them to breathe. Experts believe this sign is quite common among patients infected with COVID-19.

Headaches are particularly bothersome for those who have had this problem before the coronavirus. Moreover, the problem of headaches can bother anyone even after they have recovered from the coronavirus infection. In most cases, headache medication may have a positive effect on the unpleasant symptom.
