First, COVID-19 can cause severe inflammation, which can trigger your clotting system.

Because of its ability to prevent clots from forming, Arnica should not be taken with other medications or herbal products that can thin the blood like aspirin, clopidogrel, warfarin, enoxaparin, apixaban, dabigatran, rivaroxaban, ginger, garlic, or ginseng, to name a few.

Thrombolytics are drugs that dissolve blood clots. A doctor may give a thrombolytic intravenously, or they may use a catheter in the vein, which will allow them to deliver the drug directly to the site of the clot. Thrombolytics can increase the risk of bleeding, however.

The skin around painful areas or in the arm or leg with the DVT may feel warmer than other skin. Trouble breathing. If this happens, it could mean that the clot has moved from your arm or leg to your lungs. You may also get a bad cough, and might even cough up blood.

A pulmonary embolism happens when a blood vessel in your lungs becomes blocked. Most of the time, this blockage is caused by a blood clot and happens suddenly. Usually, a pulmonary embolism is caused by a blood clot travelling up from one of the deep veins in your body, usually in the leg.

A pulmonary embolism may dissolve on its own; it is seldom fatal when diagnosed and treated properly. However, if left untreated, it can be serious, leading to other medical complications, including death.

Symptoms

• Shortness of breath. This symptom typically appears suddenly and always gets worse with exertion.
• Chest pain. You may feel like you’re having a heart attack.
• Cough. The cough may produce bloody or blood-streaked sputum.

In general, aspirin is considered to be inferior to other blood thinners for reducing stroke risk in people with nonvalvular AFib and a CHA2DS2–VASc score of 2 or higher. When it comes to bleeding risk, aspirin is also not necessarily safer than some other blood thinners.
