Skin itching and lower back pain?

Hello, doctor.
A few months ago, I suddenly felt a tingling sensation in my mouth, and then I started experiencing itchy skin all over my body (like a prickling feeling).
I visited a dermatologist, but the medication did not improve my condition; it fluctuated between better and worse, and sometimes my skin felt cool.
I researched multiple sclerosis and found that it could potentially cause skin itching, but since I have been undergoing regular MRIs due to a brain tumor, my doctor has not mentioned any issues other than the tumor (located on the optic nerve).

I also have anxiety, autonomic nervous system dysregulation, and insomnia.
Once, after taking a sedative called Lorazepam for a while, I stopped it abruptly without realizing that I shouldn't do that.
The next day, I felt unwell, with pain in my abdominal skin and lower back, but I quickly resumed taking the sedative that night, and the next day I felt better.
At that time, I did not have the skin itching issue, but afterward, I frequently experienced pain in my abdomen or lower back.
I consulted a nephrologist, who confirmed that my kidneys were fine.
I began to wonder if my symptoms were related to autonomic nervous system dysregulation, so I started taking serotonin supplements.
However, after a month, the skin itching and coolness did not improve, although the lower back pain got somewhat better, but it returned after another month.
I found online that many internal medicine issues could also cause skin itching, but earlier this year (when I did not have the itching problem), I had an ultrasound and endoscopy done by a gastroenterologist, and in May, I had routine blood tests at the hospital, which did not indicate any specific problems.
As a side note, I have been experiencing facial numbness, tinnitus, and ear pain for about three years.
I have seen a neurologist and took steroids for over a year, and since I started taking steroids, my muscles have been twitching all over my body.
I apologize for the lengthy message.
I would like to ask: 1.
If I have skin itching, which specialist should I see? 2.
Could my skin itching be caused by abruptly stopping the sedative or by autonomic nervous system dysregulation? Thank you.

Hello Joanne: Based on the symptoms described, the tingling sensation in the mouth and the itchy feeling in the skin may be abnormal sensations caused by a neurological disorder.
These symptoms are not exclusive to multiple sclerosis; brain tumors could also cause the aforementioned symptoms.
It is advisable to discuss your condition with a physician treating brain tumors or to consult a neurologist for further evaluation.

More Info

Your symptoms of skin itching and back pain, along with the sensations of tingling and numbness, suggest a complex interplay of neurological and possibly psychological factors. Given your history of anxiety, sleep disturbances, and a previous brain tumor, it is essential to approach your situation holistically.

1. Which Specialist to Consult for Skin Itching?
Since your skin itching has not responded to dermatological treatments, it may be beneficial to consult a neurologist. Neurological conditions can manifest as abnormal sensations in the skin, including itching, tingling, and pain. A neurologist can evaluate whether your symptoms are related to nerve dysfunction or other neurological issues. Additionally, given your history of a brain tumor, it is crucial to ensure that there are no new developments affecting your neurological health. If the neurologist rules out neurological causes, you might consider revisiting a dermatologist or even an allergist to explore other potential causes, such as allergies or skin conditions that may not have been initially apparent.

2. Could Skin Itching Be Related to Stopping Sedatives or Autonomic Nervous System Dysregulation?
Yes, it is possible that your skin itching and other symptoms could be related to the abrupt cessation of sedatives, such as the medication you mentioned (Lerizine). Discontinuing certain medications suddenly can lead to withdrawal symptoms, which may include anxiety, restlessness, and physical discomfort. Additionally, your mention of autonomic nervous system dysregulation is significant. The autonomic nervous system controls involuntary bodily functions, and dysregulation can lead to a variety of symptoms, including changes in skin sensation and pain perception. Stress and anxiety can exacerbate these symptoms, leading to a cycle of discomfort.

Your experience of abdominal and back pain, which improved with the resumption of medication, further suggests that your symptoms may be tied to anxiety and the effects of medication withdrawal. The fact that your pain and itching have not improved with treatment indicates that there may be underlying factors that need to be addressed, such as stress management, anxiety treatment, or a more thorough neurological evaluation.

In summary, your symptoms warrant a comprehensive evaluation by a neurologist to rule out any neurological conditions that could be causing your skin sensations and pain. Additionally, addressing your anxiety and any potential withdrawal symptoms from medication could significantly improve your overall well-being. It may also be beneficial to explore therapeutic options for anxiety management, such as cognitive-behavioral therapy (CBT), which can help you develop coping strategies for managing your symptoms.
Lastly, maintaining open communication with your healthcare providers about your symptoms and treatment responses is crucial. This will ensure that you receive the most appropriate care tailored to your unique situation.
