Heat or Ice for sciatica?
Here is a little breakdown:
Heat can be good for sciatica, especially for stiffness and chronic pain, as it increases blood flow, reduces muscle tightness, and provides temporary relief. However, for acute, injury-related sciatica, it is best to start with ice, as heat can worsen inflammation and swelling in the initial stages. For acute flare-ups: If your sciatica is the result of a recent injury, use ice for the first 24–72 hours to reduce inflammation.
How to use ice: Apply an ice pack for 10–20 minutes at a time, several times a day. Place a cloth between the ice and your skin to prevent a burn.
How heat helps sciatica
Increases blood flow: Heat widens blood vessels, allowing more oxygen and nutrients to reach the affected area, which can promote healing.
Reduces stiffness: It can help relax tight muscles around the lower back, which may be contributing to the stiffness that comes with chronic sciatica.
Provides temporary pain relief: The warmth can help soothe the pain and make you feel more comfortable.
How to use heat therapy
Moist heat: A warm bath or a hot shower can be very effective.
Dry heat: Use heating pads, heat wraps, or heat patches, but be careful to use a low setting to avoid burns.
Duration: Apply heat for 15–20 minutes at a time, or use low-level heat for up to two hours.
Listen to your body: If applying heat causes more pain or discomfort, stop and consider switching to ice or consulting a doctor.
