Hi,
How are you? Do you still have the symptoms that you mentioned? It is good that there was improvement with the medication prescribed and decrease in the size of the spot seen in your chest x-ray. Majority of spot or nodule seen are due to benign conditions. These are quite common and may be associated with infection or  inflammation. Regular follow-up with your attending physician is highly recommended. Take care and do keep us posted.
