<s>[INST] I showed none of the symptoms of having any blood clots but I have them in my lungs and it s not hereditary so how did i get ot doctor couldn t give me an answer I wasn t driving long distance wasn t on a plane and didn t have no surgery I also played basketball that same day and didn t have no shortness of breath worked out 3 days that same week can you give me an answer [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are having Pulmonary embolism (PE). Other causes (other than you mentioned in the question) for PE are 1.  Cigarette smoking 2. Diabetes 3. Hypertension 4. Dyslipidemia (high cholesterol and triglycerides) 5. Protein C deficiency, protein S deficiency 6. Homocysteine (high levels of homocysteine) 7. Factor V deficiency. So better to consult pulmonologist and discuss these causes. You need different investigations for the diagnosis of these conditions. If you are smoker then this is the most likely cause. So quit smoking as soon as possible if you are smoker. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
