Romantic excitement and heartbreak can feel physical as well as emotional. You might notice that a new connection holds your attention, or that a breakup leaves you tense and unable to settle. Brain research offers some insight into these experiences, alongside the circumstances of your own life.
It cannot tell you who is right for you, read a partner’s intentions or turn pain medicine into a treatment for heartbreak. The useful question is how to care for yourself and make considered choices while feelings are strong.

Why a new connection can hold your attention
In a 2005 brain-imaging study, 17 people who reported being intensely in love viewed photographs of their beloved and a familiar person. The researchers found differences in activity in areas associated with reward and motivation.
This small study describes a laboratory finding. It does not provide a chemical test for love or establish that a particular relationship will be healthy or lasting.
If you are excited about someone, enjoy that feeling while leaving room to learn about them. Keep an existing plan with a friend, attend to your responsibilities and avoid making a major commitment solely because the early intensity feels convincing.
What research says about rejection and pain
Being rejected can feel deeply painful. Researchers have investigated similarities and differences between the brain’s responses to rejection and physical pain.
A 2014 study of 60 participants found distinguishable brain-activity patterns for painful heat and recalling romantic rejection, even where some broad brain regions were involved in both. Overlapping activity does not mean that the experiences are identical.
These findings are not a diagnosis of your symptoms or a reason to dismiss emotional distress. They also do not establish that a headache medicine is an appropriate treatment for a breakup.
Strong feelings still leave room for responsibility
Anger, longing and grief can be intense. They do not make threats, intimidation, repeated unwanted contact or hurting a partner inevitable or acceptable.
When a conversation becomes heated, you can ask to pause: “I need a break so I can speak respectfully. Can we return to this later?” Agree on a return time where that is safe and welcome. A pause should not become a punishment or a demand that the other person remain available.
If you are afraid of someone’s reaction, seek individual support rather than relying on a conversation to change their behaviour. You do not need a brain-based explanation before taking fear or harmful treatment seriously.
Take care of your body without self-medicating heartbreak
Stress can affect sleep and contribute to tension or headaches, as the National Institute of Mental Health explains. Regular meals, a sleep routine and contact with supportive people are practical places to start.
Do not take acetaminophen, also called paracetamol, specifically to numb emotional pain on the basis of a relationship article. The FDA warns that taking too much can cause severe liver damage. For physical pain or questions about medicine, ask a pharmacist or health professional and follow the product instructions.
Do not assume a new or severe physical symptom is simply heartbreak. Seek medical help for concerning symptoms. If emotional distress persists, worsens or makes everyday tasks difficult, a qualified mental health professional can help you consider support.
Use feelings alongside everyday information
Notice what happens beyond the strongest moments. Are your wishes heard? Are plans and limits respected? Do your expectations fit together?
Write down one feeling, one observable event and one next step. For example: “I feel disappointed; our plan was cancelled; I will ask whether we want to reschedule.” This keeps a feeling from having to answer every question about the relationship.
You can value an emotional connection while taking time to decide what you want. Biology is part of the experience; care, consent, circumstances and choices matter too.
