Body aches, weakness, dizziness, and headaches may result from excessive lactic acid production due to sudden intense physical activity after a prolonged period of inactivity, when the body fails to expel lactic acid in time. They could also be caused by infections from pathogens such as bacteria, viruses, fungi, or mycoplasma, leading to upper respiratory tract infections, bronchitis, pneumonia, or similar conditions. Additionally, systemic diseases such as systemic lupus erythematosus or rheumatoid arthritis may also cause these symptoms.
