Thanks for the query to H.C.M. Forum. Cough
All the above mentioned symptoms may be due to allergic bronchitis
This is usually due to allergens as, mite ,dust, pollen spray, fumes, smokes, hay, sudden up & down in temperature.
The fever and weakness ( in thigh ) is due to super added infection.
Take few precautions as avoidance ( mite, dust etc above ) is very important.
Antibiotics will cover infection than child will not any weakness.
Bronchodilators helps in these cases.
Coffee is also bronchodilator and give prompt relief.
