4. Ginger
Ginger is another great food that you could either eat or rub on your painful and tender knees. Whichever you choose, you’ll be happy with the result because ginger does not only taste good but it also smells great. Ginger contains an active ingredient called gingerol which is a strong anti-inflammatory substance. According to studies related to people suffering from arthritis, when ginger is added into their medication regimen, their pain is reduced even further compared to when they only take their medication. You can also enjoy ginger that’s grated in different kinds of savory meals or in making some sweet tea. There also exist some premade ginger oils which you could rub on your swollen knees directly.
