If you already get migraines, having COVID may make them worse and last longer for a period of time. It’s possible that headaches associated with long covid may be more common in people who already have a history of headaches.
Additionally, COVID can also cause a new headache that was not there before you had COVID. It may last for some time afterwards, and may need consideration of how to manage this.
Remember that being unwell with COVID and then dealing with long covid can be stressful, and stress can also be a cause of headaches.
Your clinician will go through your headache symptoms with you, to ascertain whether they feel they are potentially due to long covid or whether there may be any other causes. If they feel you need any further tests then they will discuss this with you too. They may also suggest some medication for your headache, if you aren’t taking any already or if your current medication is not effective. They may also seek advice from other specialists regarding how best to manage your headache.
In the meantime while you wait for your assessment, you can take simple painkillers for your headaches but let your GP know if you’ve been taking these for longer than a few weeks. Try not to do the things you know might make the headache worse. Try to make sure you drink plenty of water and stay hydrated, avoiding alcohol and caffeine when you can. Trying to get a restful night’s sleep might also help, as sometimes headaches can be worse when you’re tired.
