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.
That much known, only you can make the choice whether or not to quickly get another doctor, or to report to the urgent care or ER if any recurrence or complications become suspect.
Generally speaking, compression stockings do an excellent job of reducing swelling and compensating for any venous damage, especially to the valves. Many people here say their doctors prescribed 40 mm Hg or better. I discovered them on my own and became habituated to 20-30 mm Hg. If you are having extreme discomfort with one strength, it may be an option to try a lower one if that is possible. For most people it is important to wear them when there is prolonged sitting or standing, especially if driving, riding, or flying; but any extended immobility exacerbates swelling. Per my own judgment I usually forego them during weekends when I can get some variety of activity and movement.
Rarely would a doctor prescribe that they be worn at night.
Depending on if you have convalescing time, you may consider elevation in lieu of compression. Ideally, elevation involves the affected leg being higher than the heart, like on a pillow when sleeping. If that is not practical, at least stretch the leg straight when sitting instead of the foot going to the floor.
So tired of resting and elevating, never knowing when I am doing too much or too little, want to take 2 steps forward every day!
Me personally, if the stockings feel good and seem to help, I'd probably wear them. If not, I wouldn't.
