Internal vibrations or tremors can be a disconcerting symptom. Unlike external tremors, internal tremors are unseen and cannot be felt on the outside of your body. These invisible sensations are often felt in your trunk, arms, and legs. Some people also feel them in their organs even though organs physiologically cannot tremor. While internal tremors won’t cause you to spill your drink or interfere with your fine motor skills, they can be alarming. And because you can’t see or feel them externally, internal vibrations are hard to explain to others, including your doctor.
Internal body vibrations causes
There is little research on internal tremors causes. However, there is a large body of research dedicated to understanding external tremors. Most research indicates that external tremors stem from damage to the neurons that control your muscles. Damage to these nerve fibers can impact your fine and gross motor functions. Given that external tremors arise from neurological conditions such as Parkinson’s, essential tremor, and multiple sclerosis (MS), it is likely that internal vibrations are also the result that something is amiss in your nervous system.
According to one study of Parkinson’s patients, internal tremors may be linked to anxiety, especially in social settings. Yet, a growing number of women who do not otherwise have neurological conditions are speaking up about experiencing internal vibrations in perimenopause. So, could something else be at play, such as hormones? The answer is: maybe.
Is there a link between perimenopause and internal vibrations?
Perimenopause is the time leading up to menopause when a woman’s ovarian function is beginning to decline. With this general decline in ovarian function, our female sex hormones also start to decrease in our blood. The impact of our gonadal steroid hormones (primarily estrogen and progesterone) extends far beyond our reproductive organs.
We know that women have estrogen and progesterone receptors all over our bodies. And our brains have a highly complex relationship with our hormones. Thus, even subtle changes in our hormones can have a profound impact on our mood, temperature regulation, cognitive function, pain, and even our metabolism and heart rate. This is one key reason why there are 34 symptoms of perimenopause!
While internal vibrations are not considered one of the 34 recognized symptoms of perimenopause, other neurological symptoms can be caused by changing hormones:
Given the relationship between our female sex hormones and brain, there is certainly a plausible argument for internal tremors being the result of hormonal shifts in our bodies. However, the jury is still out as to whether hormones are the culprit of this irritating symptom.
What Should I Do To Manage Internal Vibrations?
If you are struggling with internal tremors, connect with your doctor to get an accurate diagnosis or to rule out any underlying causes such as MS or Parkinson’s. Before your appointment, it can be helpful to keep a journal of your experience with internal vibrations. Make sure to note:
When you experience them (for example, internal tremors at night)
How long there last
Where they are felt
What else was going on (Were you in a social situation, having work stress, or just watching Netflix…)
Information about your menstrual cycle
Unless you have a diagnosed cause of your internal tremors, your doctor may recommend you start by making some lifestyle adjustments including:
Practicing meditation and mindfulness
Getting better sleep
Avoiding caffeine and nicotine
Avoiding intense workouts and anything that increases your body heat (...we would love to toss hot flashes aside, thank you very much!)
Making dietary changes (cutting out foods you may be sensitive too such as lactose and gluten)
Because we don’t know much about internal vibrations and their causes in perimenopausal women, you and your doctor may feel stumped by this symptom if you do not have an apparent underlying cause.
While we certainly don’t have all the answers, sometimes it feels great to connect with other women experiencing the same bizarre symptoms. Join us at Perry to talk to other women experiencing internal tremors...and every other annoying symptom of perimenopause!
