Understanding Abnormal Skin Sensations
Feeling raindrops on your skin when there is no rain can be an unsettling and even alarming experience. Known medically as formication, this sensation may feel like insects crawling on the skin or water trickling even when nothing is there. While it can occur for various reasons, an underlying pinched nerve or neurological condition are often at the root.
What Causes Fake Raindrop Sensations?
Formication has several potential causes:
- Medication side effects
- Drug or alcohol withdrawal symptoms
- Vitamin deficiencies
- Diabetes
- Lyme disease
- Liver or kidney failure
- Neurological disorders like multiple sclerosis, Parkinson's disease, or fibromyalgia
However, the most common reason behind feeling raindrops on skin with no rain around relates to nerve issues in the body. Irritated nerves misfiring can make the brain think sensations are occurring when they are not actually happening.
Pinched Nerves and Radiculopathies
When the nerves exiting the spine become compressed or inflamed, it is known medically as a radiculopathy or pinched nerve. Common causes include herniated discs, bone spurs, arthritis, or poor posture.
Radiculopathies frequently occur in the:
- Neck (cervical area)
- Lower back (lumbar area)
- Wrists (carpal tunnel area)
Depending on the location of nerve inflammation, different odd skin sensations can occur like feelings sparks, ticks, pricks, tinglings, or wetness in the absence of real stimulation.
How Pinched Nerves Cause False Raindrop Feelings
Nerves relay tactile information about temperature, pressure, texture, pain and more from the skin to the brain. When a nerve gets irritated and begins misfiring, wires get crossed. The brain struggles to properly interpret the signals leading to fake or exaggerated skin sensations.
These false signals feel quite realistic, explaining why pinched nerves can make you feel raindrops falling when no moisture in in the air. The brain thinks the nerve sensations truly represent water on the skin.
Fibromyalgia and Multiple Sclerosis
Besides acute nerve compression issues, some chronic illnesses attack nerves over longer periods contributing to skin sensations with no apparent cause:
Fibromyalgia-Related Formication
Fibromyalgia involves increased nervous system sensitivity with amplified reactions to various inputs. Nerves misfire and overreact to even minor stimuli.
This dysfunction causes tingling skin, prickling feelings, and numbness. Fibro patients often describe fake dripping water when nerves go haywire. Managing fibromyalgia requires a multifaceted approach combining medications, lifestyle changes, therapy, massage, acupuncture and more.
Multiple Sclerosis and Raindrop Sensations
In multiple sclerosis (MS), insulation protecting nerves slowly erodes leading to miscommunication within the body’s electrical system. Signals get lost or experience interference like a damaged wire.
MS malnutrition impacts skin sensations in various ways. Numbness, burning feelings, tingling, tightness, coldness or perceived motion like water flowing can manifest anywhere on the body. MS treatment revolves around immune-modulating medications and symptom management.
Seeking Treatment for Abnormal Skin Sensations
Unexplained raindrop or water trickling feelings deserve medical assessment for proper diagnosis and treatment. Beginning with your general practitioner is wise for initial analysis and potential referrals to specialists.
Depending on findings from physical examinations, medical history and testing, doctors may recommend additional follow up with neurologists, physiatrists, rheumatologists or pain management physicians.
Steps in the Diagnostic Process May Include:
- Imaging tests like MRI to visualize spine, nerves and central nervous system
- Bloodwork to uncover potential vitamin shortages, diabetes, thyroid dysfunction, autoimmune illnesses, infections explaining nerve dysfunction
- Nerve conduction velocity examination to analyze electrical signaling through nerves
- Treatment trials with medications alleviating nerve-related symptoms
Based on what diagnoses reveal as the reason behind false raindrop or dripping water feelings on skin, personalized treatment plans can be created to reduce formication occurrences.
Possible Treatments for Abnormal Raindrop Sensations
Specific treatments depend on causation but may potentially involve:
- Prescription medications - anticonvulsants, antidepressants, immunotherapy, vitamins, etc.
- Nerve blocks
- Physical therapy
- Healthy diet and lifestyle changes
- Counseling and therapeutic techniques for chronic diseases
- Surgery - carpal tunnel, spinal procedures, etc.
- Alternative approaches - acupuncture, massage, electromagnetic stimulation, etc.
While feeling raindrops on skin with no rain around can stem from multiple explanations, when traced back to underlying nerve issues, targeted treatments can help minimize occurrences of this unwelcome formication.
