I have a DVT factor 8, had this condition for 11 years. I have had pressure in my chest. I have a greenfeather filter. Today I went to the emergency room. They did test and stated after testing INR result was 0.97 low. No clots. They upped my coumadin after being on only 2.5 to 5.0. That was Wednesday. MY INR has not raised, I am worried about why it has not raised. I was sent home told to contact my doctor on Monday. Nothing was given to me to raise it. They did cat scan and testing and found nothing including a blood clot. I have been on 2.5 Mg. for a year. I have not had my INR checked until two weeks ago because the doctor I use to have said it was ok for six months to not have it checked. My new primary said that was not correct. Two week s ago I had a blood clot that the filter did catch. Was taken to Freeman Hospital where they did test, and even a echo of my heart, while doing a stress test. They said it was heart burn!!!! My primary said that was ridiculous that it sounded like I had passed a clot that the filter did catch. Never had this close of a call. Today the right side of my tongue swelled for no reason. The emergency doctor said it (the tongue swelling) was probably something due to an allergic reaction. I am not allergic to anything!!! They found nothing sent me home saying to talk to my primary. I am 42 years of age female never smoked, been in great health. Now these items are coming up. I am scared these doctors are not finding what is wrong even with my condition. Why would my right side of my tongue swell during this?

### output:

Hello, I can understand your concern. It seems that the swelling of tongue that you have developed has nothing to do with the DVT and pressure in chest you are having. I agree with your doctor that it seems to be an allergic reaction. I would advise you to take Antihistamine such as Levocetrizine 5 mg (Exocet) or Loratadine 10 mg (Forfeits) once a day for at least 5 days. If it was an allergic reaction, you should find immediate improvement in the swelling in 1-2 days. Otherwise, the cause is not allergic. The allergy could be due to anything that you have been exposed to through air, water or food. If the episodes are frequent, you should go for a blood test for allergy to find out what substance you are allergic to, and you can avoid exposure to that in the future. However, if the swelling does not decrease with the antihistamines or if it increases, then you should consult a dentist to examine the oral cavity and investigate further regarding the cause. I hope this information helps you. Thank you for choosing Chat Doctor. I wish you feel better soon. Best,
