@brenda1231, I hope you saw @carriebythesea's helpful response to your very good question: "How will one know the clots in the lung has dissolved?"

I found this article is also helpful in explaining:
- How Do Blood Clots Dissolve? https://www.webmd.com/dvt/dissolve-blood-clot

A couple of key points from the article:
- Blood thinners don’t dissolve the clot, but they can stop it from getting bigger and keep new ones from forming. That gives your body time to break up the clot.
- Thrombolytics. These clot-busting drugs are used for serious conditions, like a pulmonary embolism. Unlike blood thinners, they do break down the clot. They work by turning on plasmin, which jump-starts your body’s natural process for clearing things out.
- A DVT or pulmonary embolism can take weeks or months to totally dissolve. Even a surface clot, which is a very minor issue, can take weeks to go away.
- If you have a DVT or pulmonary embolism, you typically get more and more relief as the clot gets smaller. The pain and swelling from a DVT usually start to get better within days of treatment.
- Symptoms from a pulmonary embolism, like shortness of breath or mild pain or pressure in your chest, can linger 6 weeks or more. You might notice them when you’re active or even when you take a deep breath. Exercise can help with this.

Brenda, can you share more about you? Are you taking medication to resolve a blood clot? What symptoms are you experiencing?
