Severe thigh muscle pain lasting three months despite taking Aceclofenac, Paracetamol, and vitamin B12 injections suggests that the cause might not be simple inflammation or vitamin deficiency alone.

🩺 Possible Causes

• Muscle strain or overuse injury that has not healed properly.
• Nerve-related issues such as sciatica or lumbar spine problems causing referred pain.
• Underlying conditions like muscle disorders, chronic inflammation, or metabolic issues that require further evaluation.

🩺 Recommended Next Steps

• See a specialist doctor, such as a neurologist or an orthopedic doctor, for a detailed physical exam and possibly imaging (like MRI) or nerve studies.
• Blood tests to check for muscle enzymes, inflammation markers, or other systemic causes may be needed.
• Avoid self-medicating further without diagnosis, as persistent pain needs targeted treatment.
