The cause of your symptoms can be inflammation going on in your body along with fever
You may be suffering from bronchitis
, as it is common in smokers. The feeling of weakness and shakiness may be due to the accompanied fever. Check your fever and pulse. Are you taking some medicines for blood sugar? Low blood sugar
can contribute to these feelings. Normally the blood sugar level does not lower below normal as the body has built-in mechanisms to bring the sugar level up. If i was your treating physician i will do the following If you have productive cough
, fever, weakness and shakiness:
1. Blood complete picture.
2. Blood sugar random
3. Chest X-ray
and will consider starting an antibiotic, if sugar is normal and blood picture and fever indicate infection.
