I'm sorry to hear that you've been experiencing pain in your upper and middle back. It's possible that the massage you received at the salon may have aggravated an underlying issue, leading to the pain you're currently experiencing.
Given that you've already seen multiple doctors and tried medication and physiotherapy without improvement, it may be worth seeking a second opinion from another doctor or specialist. It's also possible that your
diabetes may be contributing to the pain, as high blood
sugar levels can cause inflammation and nerve damage.
Here are some possible causes and treatments for your back pain:
Muscle strain or sprain: This is a common cause of back pain, especially after physical activity or trauma. Treatment may include rest, ice/heat therapy, over-the-counter pain relievers, and gentle stretching exercises.
Pinched nerve: This occurs when a nerve in the spine is compressed, often due to a herniated disc or spinal stenosis. Treatment may include physical therapy, medication, or surgery in severe cases.
Arthritis: This is a chronic condition that causes inflammation and pain in the joints, including the spine. Treatment may include medication, physical therapy, and lifestyle changes (e.g. weight loss, exercise).
Fibromyalgia: This is a chronic condition characterized by widespread pain and tenderness in the muscles and joints. Treatment may include medication, cognitive behavioral therapy, and gentle exercise.
Stress and anxiety: Emotional stress and tension can cause muscle tightness and pain, including in the back. Treatment may include stress management techniques, counseling, and relaxation exercises.
I would advise discussing these potential causes and treatment options with your doctor, and potentially seeking a referral to a specialist if necessary. In the meantime, it may be helpful to try gentle stretching exercises, hot/cold therapy, and relaxation techniques to help manage your pain.
