Hello,
Pain in the lower side of the abdomen is common because of
diverticulitis but can be due to gastritis or indigestion. Take fiber in the diet, adequate water & avoid
constipation. You can take antacids & PPI's like
Pantoprazole. Take
Acetaminophen (Tylenol) for pain.
Since you have a history of addiction to smoking & now you are coughing out black specks, it is a cause of concern. Smoking causes your phlegm to thicken causing more coughing. When dangerous chemicals in the cigarettes get lodged in the airways of your lungs, it causes your mucus & phlegm to become dark. Get physically examined, get Sputum test, CBC, Tissue sampling, Imaging (CT/PET) & Lab. tests done to rule out COPD & lung cancer. The pain in the left side can be due to the metastasis on the left side.
You will be treated on the basis of the diagnosis (Medications,
Chemotherapy, Targeted therapy, Radiation therapy or Surgery). Get treated at the earliest.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K,
General & Family Physician
