Heat and tingling in the upper body, forearms, and calves?
Hello, Doctor.
In the evening, I fall asleep but suddenly experience a sensation of heat and tingling in my upper body, forearms, and calves.
The feeling of heat is intense, almost like I am about to have a fever, and once it occurs, it can last for an entire day up to a week before returning to normal.
This has been happening for over six months.
Could you please help me understand what might be causing this? Is it related to a neurological disorder? If not, which specialty should I consult? I have been troubled by this for a long time.
Thank you!

Although this symptom is not very typical, it may still indicate a type of sleep disorder, with restless legs syndrome being the closest match.
While it can also occur in the upper body and forearms, restless legs syndrome in some patients may not be limited to the legs; it can manifest in other parts of the body as well.
This condition typically occurs when falling asleep, characterized by sensations of discomfort, itching, or crawling deep within.
Generally, it is advisable to first check for any liver or kidney issues, as well as conditions such as iron or magnesium deficiency.
This is not significantly related to previous medication use.
Symptoms such as nerve pain and heat should still be evaluated by a neurologist.

Dear Patient,
Thank you for sharing your concerns regarding the episodes of upper body heat and tingling sensations in your forearms and calves. It’s understandable that these symptoms can be quite distressing, especially since they have persisted for over six months. Let’s delve into the potential neurological concerns and other possible explanations for your symptoms.
The sensations you describe—heat and tingling—can be indicative of several underlying issues. Neurologically, these symptoms may suggest peripheral neuropathy, which is a condition that affects the peripheral nerves and can result from various causes, including diabetes, vitamin deficiencies, or even autoimmune disorders. Peripheral neuropathy often manifests as tingling, burning, or numbness in the extremities, and it can be exacerbated by certain positions or activities.
Another possibility is that your symptoms could be related to a condition known as multiple sclerosis (MS), which can cause a wide range of neurological symptoms, including sensory disturbances. However, MS is typically accompanied by other symptoms such as muscle weakness, vision problems, or coordination issues. If you have not experienced these additional symptoms, it may be less likely that MS is the cause.
Additionally, the episodes of heat you experience could be linked to anxiety or stress. The body’s response to stress can sometimes lead to physical sensations such as warmth or tingling, particularly if you are experiencing heightened anxiety levels. This is often referred to as psychosomatic symptoms, where psychological factors manifest as physical symptoms.
Given the duration and nature of your symptoms, it is advisable to consult with a neurologist. A thorough neurological examination, along with appropriate diagnostic tests such as nerve conduction studies or imaging (like MRI), can help determine if there is any underlying neurological condition contributing to your symptoms.
If the neurologist rules out neurological causes, you might also consider consulting with an internist or a rheumatologist, especially if there are concerns about autoimmune conditions or systemic issues that could be affecting your nerves.
In the meantime, keeping a symptom diary can be beneficial. Documenting when the symptoms occur, their duration, any associated activities, and other relevant factors can provide valuable information to your healthcare provider. Additionally, managing stress through relaxation techniques, exercise, or therapy may help alleviate some of the symptoms if they are stress-related.
In conclusion, while your symptoms could be related to a variety of conditions, a thorough evaluation by a healthcare professional is essential to determine the exact cause and appropriate treatment. Please do not hesitate to seek medical attention, as early intervention can often lead to better outcomes.
Wishing you good health and relief from your symptoms.
Best regards.
