what can be the cause of constant vibration in chest? I am not an anxious person

Hello, guest.

Experiencing a persistent vibration feeling that remains undiagnosed despite numerous medical consultations can indeed be distressing and confusing. Since your tests, including heart evaluations and an MRI of the brain, have returned normal results, and specialists like a neurologist haven't pinpointed a cause, it's understandable that you feel frustrated and anxious about this unexplained symptom.

One possibility to consider, especially in the absence of physical findings, is a sensory phantom sensation. These are sensations that feel very real to the person experiencing them but don't have a detectable physical cause. They can be influenced by various factors, including stress or fatigue. Notably, you mention noticing it more at bedtime when it's quiet, which could suggest a sensory hypersensitivity or heightened awareness of bodily sensations during quiet, less distracting moments.

Another aspect to consider is the role of psychological factors. Even if you don't generally consider yourself an anxious person, ongoing unexplained symptoms can cause or exacerbate anxiety. This anxiety, in turn, can make you more aware of or sensitive to the sensation, creating a cycle that's hard to break.

Sometimes, conditions or symptoms that are initially hard to diagnose become clearer over time. Additionally, you might explore avenues like stress management, relaxation techniques, or even cognitive-behavioral therapy (CBT) to help cope with the distress and discomfort caused by this sensation.

Remember, your experience is valid even if a clear medical explanation hasn't been found yet. Taking a holistic approach that considers both physical and psychological aspects could be a constructive way forward.

I wish you luck in your journey to find the cause of the issue.
