Thanks for writing in.
I am a qualified and certified cardiologist. I read your mail with diligence. I find your calf pain could be due to deep venous thrombosis
which lead to pulmonary thromboembolism
+ running out of breath). If you are overweight
and usually sedentary in your habits that only would strengthen the suspicion. I would urge you to see a doctor who will thoroughly examine you and get certain tests like ultrasound for DVT (deep venous thrombosis) and specific test for PTE (Pulmonary Thromboembolism) done. Thereafter, treatment will be started.
As you are a patient of hypertension
too. So, no time should be wasted and you ought to go to ER for seeing the doctor so that you can be
attended to on urgent basis, an EKG will exclude any cardiac complications.
If this is the diagnosis you should be fine in a few days time. Good Luck.
