Thank you for your query on Healthcare Magic.
Exhaustion, sore muscles, and swollen lymph nodes
are seen in viral fevers, mononucleosis
, and other nonspecific infections.
I suggest you to take Tylenol
in prescribed dose for your symptoms.
Consult the physician for clinical examination to look for any focus of infection.
Initial investigations like complete blood picture, sedimentation rate,and if needed lymph node biopsy
has to be done after clinical examination to look for the cause.
Hope I have answered your query.
