I assume you mean “generalized weakness”? If so, the doctor needs to know at least your age, medical, and social history. To answer a simpler way, I would be looking for blood count, chemistry, and iron studies very first. Without the above, it’s nearly impossible to offer a ”treatment plan.”
Needs urine dipstick and ironed analysis and culture.
I tried to answer your question and would like to get your feedback for possible continuation of our conversation, but I don’t get it, why?
List of possible cold complications are broad,but pneumonia must be ruled out first.
Rapid Strept test and throat swab for bacterial culture are needed to decide if treatment is needed.
General precautions required for affected person and relatives.

Imporatant to know your medical history,family history,do detailed physical exam.

Best to see a doctor.
