One thing I forgot to ask you, were you given the D-Dimer blood test. Its a simple early warning that trouble from a clot may be in your body. If the results are above 0.5(zero point five) it could indicate you have a clot your body is trying to dissolve. Mine was 3.66 but age can cause it to read higher. Unfortunately, I didn’t need a test to tell me I had a clot in my right lung, the excruciating pain told me that.
