Here are some popular options and what you need to know if you’d like to give them a try.
Analgesic Creams, Rubs, and Sprays
Topical painkillers, or analgesics, are sprayed on, rubbed in, or applied as patches onto the skin over painful muscles or joints. Although all are designed to relieve pain, different products use different ingredients. Here are some of the most common.
- Counterirritants. Ingredients such as menthol, methyl salicylate (oil of evergreen), and camphor are called counterirritants because they create a burning or cooling sensation that distracts your mind from the pain.
- Salicylates. These same ingredients that give aspirin its pain-relieving quality are found in some creams. When absorbed into the skin, they may help with pain, particularly in joints close to the skin, such as the fingers, knees, and elbows.
- Prescription NSAIDs. Topical forms of nonsteroidal anti-inflammatory drugs have fewer of the typical NSAID side effects, like stomach upset and bleeding. Don’t use them if you’re also taking oral NSAIDS.
- Capsaicin. The main ingredient of hot chili peppers, capsaicin is also one of the most effective ingredients for topical pain relief. It can be helpful for joint pain and for diabetic nerve pain. When first applied, capsaicin creams cause a warm tingling or burning sensation. This gets better over time. You may need to apply these creams for a few days up to a couple of weeks before you notice relief from pain.
- Lidocaine. This medicine numbs pain. It comes as a gel or a patch that you apply to the painful area. Talk to your doctor first if you have liver problems or take heart rhythm drugs.
Here’s what you need to know to get the greatest effects and minimize the risks of these products:
- Read the package insert and follow directions carefully. If there is an insert, save it to refer to later.
- Never apply them to wounds or damaged skin.
- Do not use them along with a heating pad because it could cause burns.
- Do not use them under a tight bandage.
- Wash your hands well after using them, or wear gloves. Avoid touching your eyes and genitals with the product on your hands.
- If you are allergic to aspirin or are taking blood thinners, check with your doctor before using topical medications that contain salicylates.
Hot Packs and Cold Packs
Hot or cold packs — or sometimes a combination of the two — can provide relief for sore muscles and joints.
Cold numbs sore areas. It is especially helpful for the pain and swelling of an arthritis flare or joint injury, such as a sprained ankle. Cold may reduce inflammation by constricting blood flow to the injured area.
You can apply cold using a commercial cold pack or with a water bottle filled with ice and cold water.
You can also use items already in your home such as:
- Zippable plastic freezer or storage bags filled with ice and water
- A washcloth or hand towel dipped into cold water and ice
- A bag of frozen vegetables, such as peas or corn
Heat packs relax your muscles. Heat dilates blood vessels, sending more oxygen and blood to the area. Heat also decreases the sensation of pain.
You can apply heat with commercial heat packs, heating pads, or hot water bottles. Other ways to use heat include:
- Soaking in a hot bathtub
- Standing under a hot shower
- Soaking a washcloth or hand towel in warm water then applying to painful joints or muscles
To get the most relief from hot or cold without damaging your skin, try these tips:
- Use either heat or cold for only 15-20 minutes at a time.
- Place a towel between your skin and the cold or heat source.
- Don’t use heat or cold on skin with open cuts or sores.
- Don’t use cold packs if you have vasculitis or poor circulation.
- Test the temperature before using heat or cold.
- Do not use creams, heat rubs, or lotions on your skin while using a hot or cold treatment.
- Be especially careful with heating pads, which can cause severe burns if too hot or if left on for too long.
- Do not make your bath or shower water too hot. This may cause dizziness or fatigue.
