This is Dr Basu, Experienced Specialist.
I am here to address your concerns and provide great service.
But your blood pressure
is moderately high so does the pulse rate.
So definitely something is seriously wrong.
Blood clot in the lungs
or pulmonary embolism
can cause all these symptoms.
Underlying myocardial infarction also can cause them.
Aortic aneurym is another possibility.
CT angiogram of the chest along with a nuclear stress test should be considered.
Now you may also have herniated disc in your spine which can cause radiating pain from nerve impingement.
That work up is considered with MRI scan of the spine after full heart and lung work up.
I will suggest you to go to ER if possible.
Thank you for sharing your concerns with us today. If you have any additional questions or need further clarifications, please do not hesitate to ask. I am here to answer them. I wish you good health. Regards, ***** *****
