Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have fatigue , headache and breathlessness . Well there can be many reasons for symptoms you mention in query like sinusitis , diabetes, type 2 , multiple sclerosis , stress reaction ,
tension headache , medication reaction or side-effect , anemia . It could be due to cardiac problem like stroke or pacemaker problem as you mention in query . I would suggest you to
consult cardiologist for proper examination without any delay . Doctor may order blood test , ECG , troponin t test and take history . Doctor may also refer him to
ENT specialist in case of sinusitis related problem . Doctor may order CT scan and examine ear with otoscope . Doctor may prescribe antibiotics like amoxicillin , along with sedative and supplements like
ginkgo biloba . For now take ibuprofen or
acetaminophen for pain , take proper rest , do not exert your body and eat iron rich food like spinach .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
