Hope that everything has been sorted out and you are now OK.
Best wishes.
Thank you everyone for the replies. I very much appreciate it.
As you are experiencing the jaw, ear, headaches, and chest problems sounds like you now have a respiratory infection.
As you have had problems with your teeth since your pregnancies, it is likely that these have cavities and need to be looked at by the dentist. If you have not had your wisdom teeth come through, these too can be bothersome. And there is a possibility of abscesses. So you will need to see the dentist to get these sorted out.
But as you are complaining of headaches and earache as well as chest pains, it sounds that you have an infection in your ear and chest. You would be wise to see a doctor to check your ear and chest for infections who may find that you may need a course of antibiotics.
In the meantime you can take pain relief as recommended on the packet for your pains.
Keep warm and drink plenty of fluids, avoiding milk products because the promote the production of mucus.
Best wishes
I had the same problem. I was diagnosed with tmj. that is where your jaw joint in front of your ear. it goes all the way down your neck to your shoulder. it really hurts. mine got to popping loud. it has gone into arthritis. maybe this could be your problem. mandy876
Could be the Thyroid. If you can, run some tests for TSH, T3 and T4.
I have a thyroid nodule on my right lobe and the ear pain is barely tolerable. Some symptoms of hyperthyroidism include heart palpitations and arrhythmia. Hyperthyroidism can be common after pregnancy.
