I Thought It Was From Bad Air Quality — My Lung Was Filled With Clots: Shawna’s Story

I Thought It Was From Bad Air Quality — My Lung Was Filled With Clots: Shawna’s Story

Listen to Your Body

During fire season in Southern California, I was experiencing shortness of breath that I attributed to bad air quality.


It Got Worse

As the week progressed it got worse and I began to feel pain in my back.

By Friday, I felt a sharp stabbing pain in my back anytime I took a breath.

I first thought it was sore because of my struggle to get in a deep breath.


Urgent Care

My husband took me to urgent care.

They did a chest x-ray and realized my right lung was very scrunched up.

They thought my gallbladder was inflamed.

They sent me to the ER for what they said would be a gallbladder removal.


The ER

When I got to the ER they ran a lot of tests.

One revealed my gallbladder was fine.

But they found that my right lung was filled with clots.

They were unexplained since I wasn’t on birth control, had no recent injuries or travel.

I was admitted.


Finding the Cause

It wasn’t until a month later — after mammograms and so many blood tests — that we found out I have a Factor II blood mutation.

My older sister and her daughter have both tested positive, as well as my mother.


Life After

I was able to get off blood thinners at my six month check after working hard to change my lifestyle.

I have had no recurrences of clots again.

I lead an active lifestyle now and pay more attention to movement and using compression when needed.

I workout 6-7 times a week.

I move my body every hour and take breaks when in the car for a long time.

I’m conscious of my movement and getting my blood moving and heart pumping.


What I Want Others to Know
