Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
I'd check with your doctor to see if he thinks it's PE related. I'd also just do a check on what you're life has been like over the last few months and see what's changed, like have you started certain meds (prescribed or over the counter) that may make your BP go up. I'd see too if your sodium intake has increased, is there weight gain, lack of exercise, stress, etc. These can play a role in high BP. Normal aging can also play a role, as can genetics.
If your BP actually high, or just higher than normal for you? Is it something your doctor is concerned with and talking to you about? If s/he wants you to start medication for it but you don't want to, then discuss strategies with your doctor for how you can try to lower it without medication, but basically that will always start with lower sodium intake, so if you're not already doing that then maybe give it a try. But just another thought - I felt probably the most stressed about the PE at around the three month mark for recovery. If you're only checking BP when you see the doctor, maybe it could just be that the situation is stressful for you and going to the doctor doesn't help. However, if your doctor is concerned, do take the situation seriously, because of course untreated high blood pressure can cause some terrible problems of its own.
