Chronic nephritis cold should pay attention to rest, drink an appropriate amount of water, apply cold medicine or a variety of antiviral Chinese medicine oral solution and other treatment. For patients with chronic nephritis, if you have a cold, you should first pay attention to rest and avoid exertion, the process of rest is the gradual recovery from the cold, and you should also pay attention to drinking the right amount of water. The reason why I say drink water in moderation is because many patients with chronic nephritis have edema symptoms, and if you drink too much, it may cause edema to worsen and blood pressure to rise further. If you do not drink water, it is also not good for the recovery of the cold, so you can drink water in moderation, especially warm water. If patients have symptoms such as septic infection of the tonsils, they can be treated with antibacterial drugs such as amoxicillin or azithromycin under the guidance of a doctor, which are basically not nephrotoxic and are safe for patients with chronic nephritis. For patients with sore throat, you can also take the appropriate amount of heat-clearing and detoxifying Chinese medicine oral liquid, which basically has no effect on the kidneys when taken in moderation.
