thanks for your query.
dont take marijuana for pain relief in pulmonary embolism
you dont have to take any analgesic
really to relieve your pain due to pulmonary embolism rather you have to be treated properly for pulmonary embolism. Start the heparin
therapy with anticoagulation in the form of warfarin
or decoumarin group of drugs with maintenance of INR beween 2 to 3. Ask your doctor to find out the cause for pulmonary embolism and treat that.
