Yes, it is generally safe and very common to take a muscle relaxant alongside diclofenac (the active ingredient in your current medication). This combination is frequently prescribed to target both the inflammation and the muscle spasms causing your back pain. However, combining them can increase side effects like drowsiness, dizziness, or mild stomach upset. To ensure safety, please consult your doctor or pharmacist to choose the appropriate muscle relaxant and dose, especially if you have a history of stomach ulcers, kidney issues, or are taking other medications. Avoid driving or operating machinery if you feel drowsy.

Severe tooth pain can happen because of tooth decay, cavity, gum infection, wisdom tooth problems, sensitivity, or infection around the tooth root. The pain may become worse while eating, drinking hot or cold items, or lying down. Pain medicines may provide temporary relief, but the underlying dental problem usually still needs proper treatment, such as cleaning, filling, root canal treatment, or treatment for gum infection. Medicines commonly used for temporary tooth pain relief may include paracetamol or anti-inflammatory pain medicines, but the right choice depends on your age, stomach health, kidney function, allergies, and other medical conditions. Avoid taking repeated painkillers or antibiotics without proper dental advice because this may only mask the pain without treating the actual cause. Warm saltwater rinses, maintaining oral hygiene, avoiding very cold or sugary foods, and not chewing on the painful side may help reduce irritation. Do not place painkiller tablets directly on the tooth or gums because this may burn the tissues. Consult a dentist soon if swelling develops, fever occurs, pus appears, or the pain becomes severe enough to disturb sleep or eating.

For a giant cell tumour where standard pain relievers and nerve medications are not providing relief, there are effective, targeted pharmaceutical options available. A specialised medication called denosumab is a monoclonal antibody that directly targets the tumour cells, which can significantly shrink the tumour and relieve pain. Additionally, bisphosphonates like zoledronic acid can help strengthen the bone and reduce discomfort. For immediate pain management, your specialist may consider prescribing stronger pain medications, such as tapentadol or other targeted analgesics. Please consult your oncologist or orthopaedic specialist to safely discuss these advanced medical alternatives.
