I'm sorry to hear that you're experiencing severe lower back pain during activities like bathing or sitting on your toes. This type of pain can arise from various causes such as muscle strain, nerve irritation, or issues related to the spine or joints.

Here are a few points to consider:

• Posture and Movement: Certain positions or movements may put extra stress on your lower back muscles or spine, leading to pain.
• Muscle or Ligament Strain: Sudden or awkward movements can strain muscles or ligaments in the back.
• Underlying Conditions: Conditions like sciatica, herniated discs, or arthritis can cause pain triggered by specific activities.

Since your pain is severe and linked to specific actions, it is important to have a thorough evaluation by a specialist, such as an orthopedic doctor or a spine specialist. They can perform a physical examination and may recommend imaging studies if needed to identify the exact cause.

In the meantime, over-the-counter pain relievers like the Acton-OR Tablet (a painkiller and fever reducer) may help manage mild to moderate pain, but you should use them only as advised by a doctor.

Recommendation: Please consult an orthopedic specialist promptly to get an accurate diagnosis and appropriate treatment plan tailored to your condition. If the pain worsens, is accompanied by numbness, weakness, or bladder/bowel issues, seek emergency medical care immediately.To narrow down potential causes, we will need some more information.Could you please tell me your age and gender?
