There are two types of muscle pain after catching a cold: those who have a cold and those who have a rheumatic disease.
If the muscles all over the body are painful, it is mostly a case of having a wind-cold, and the cold causes muscle contraction leading to symptoms of muscle pain, which can be treated with Chinese medicines for wind-cold such as Jiu Wei Qiang Wu Tang and Gui Zhi Granules, or you can take appropriate rest after taking warmth measures without medication and wait for its natural recovery.
