Loss of Sensation in Skin: Possible Causes and Solutions

The surface of the skin seems to have lost its tactile sensation?

Hello Doctor, I was hospitalized for a week due to gastrointestinal issues and received intravenous fluids and antibiotics.
It has been two weeks since my discharge.
However, since then, I have noticed that the skin on my left arm near the shoulder seems to have lost its superficial sensation.
The affected area does not feel unusual, but when I apply the same amount of pressure to other areas of my skin compared to the affected area, it is noticeably more numb, and I cannot feel normal touch or pain sensations.
Recently, I have been getting massages and using medicated patches, which seem to help a little, but the issue remains the same.
Could this be due to prolonged pressure while sleeping (I tend to sleep on my side)? I would like to seek your advice, thank you for your assistance.

It is likely a case of nerve compression; however, since there is no muscle weakness, it may be caused by a sensory branch of the axillary nerve.
Avoiding further compression should lead to gradual recovery.
Of course, it could also be a case of mononeuritis.
If symptoms occur without compression or if there is unexplained numbness or weakness in other areas, further evaluation and treatment by a physician will be necessary.

More Info

Loss of sensation in the skin, particularly in a localized area such as your left arm near the shoulder, can be concerning and may arise from various underlying causes. Given your recent hospitalization and treatment with antibiotics, it's essential to consider several factors that might contribute to your symptoms.

Possible Causes
1. Nerve Compression or Injury: One of the most common reasons for localized loss of sensation is nerve compression or injury. This can occur due to prolonged pressure on the nerves, especially if you have a habit of sleeping on your side. The brachial plexus, a network of nerves that innervates the arm, can be compressed, leading to numbness or tingling sensations.

2. Peripheral Neuropathy: This condition involves damage to the peripheral nerves and can result from various factors, including diabetes, infections, or even certain medications. If you were on antibiotics, it's worth considering whether they might have contributed to nerve sensitivity or damage.

3. Circulatory Issues: Reduced blood flow to a specific area can also lead to numbness or a loss of sensation. If you have been less active during your recovery, this could contribute to circulatory problems.

4. Post-Hospitalization Effects: After a significant illness or hospitalization, your body may take time to recover fully. This can include temporary changes in nerve function or sensitivity.

5. Psychological Factors: Stress and anxiety, especially following a health scare, can manifest physically, including changes in sensation.

Solutions and Recommendations
1. Consult a Specialist: Given the complexity of your symptoms, it would be prudent to consult a neurologist. They can perform a thorough evaluation, including nerve conduction studies or imaging, to determine if there is any nerve damage or compression.

2. Physical Therapy: Engaging in physical therapy can be beneficial. A physical therapist can provide exercises to strengthen the muscles around the affected area and improve circulation, which may help alleviate symptoms.

3. Posture and Sleeping Position: Since you mentioned that you sleep on your side, consider adjusting your sleeping position. Using a supportive pillow or changing your sleep posture can help reduce pressure on the nerves.

4. Massage Therapy: While you have already tried massage, it may be worth continuing, as it can improve circulation and relieve muscle tension that may be contributing to nerve compression.

5. Monitor Symptoms: Keep a diary of your symptoms, noting any changes or patterns. This information can be valuable for your healthcare provider in diagnosing the issue.

6. Lifestyle Adjustments: Ensure you are maintaining a healthy lifestyle, including regular exercise, a balanced diet, and staying hydrated. These factors can significantly impact nerve health and overall recovery.

7. Pain Management: If you experience discomfort, over-the-counter pain relievers may help, but consult your doctor before starting any new medication, especially considering your recent health history.

Conclusion
Loss of sensation in the skin can be a multifaceted issue, often requiring a comprehensive approach to diagnosis and treatment. Given your recent hospitalization and the symptoms you describe, it is essential to seek professional medical advice to rule out any serious underlying conditions. Early intervention can lead to better outcomes, so do not hesitate to reach out to a healthcare provider for further evaluation.
