synthroid and a high d-dimer and FDP

[margie61]

In April of this year I was in the ER department because my thyroid medication was lowered and changed to a generic that I can not take.  I had palpatations.  All my lab work came back normal except my d-dimer it was 1832.  I had it repeated in a few days and it was 1799 not much of a difference.  Two weeks past and I had it repeated again it dropped 1273.  I then had a dentist appointment and had a tooth filled, and then went to a chiropractor and had a deep muscle massage.  I then needed my thyroid testing done and asked  for a repeat d-dimer and it was up to 2000.  I am in the process of having Factor V,  FDP,Protein S and C, MFTM(?) done. The protein S and FDP came back high.  I am really scared! Can you please advise me.  Thank you very much.

I don't think the thyroid is linked to the other lab results -- would see a hematologist to sort this out.

This is margie61.  I would like to add to my post that I was rear ended in a car accident in 2008 and have been having back problems ever since.  Can this contribute to the high d-dimer and FDP also?
