Hi,
All the present symptoms are suggestive of gastrointestinal disturbance, GRD and so on.
I would advise you the following:
Consult your Doctor again for a proper clinical evaluation, examination and get investigated accordingly like tests of blood for CBC, liver and other organ functions,
ultrasonography and so on.
Also get started on symptomatic management with a PPI like
Omeprazole,
Domperidone and antacids for nausea.
Painkillers and other medications as needed.
If this does not give complete relief then stool tests, further specific blood and urine tests and other investigations like Upper GI
Endoscopy will help to give you the proper diagnosis and gives plan of further management.
This may not be related to
pregnancy or removal of Mirena.
Take care.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, ENT & General Surgeon
