Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have severe tiredness along with
blurred vision and sweating . Well there can be many reasons for symptoms you mention in query like side effect of certain medications ,
rheumatoid arthritis ,
viral syndrome , hormonal imbalance , in some cases the symptoms also infections, sleep apnea, acid reflux, and
hypoglycemia . I would suggest you to consult general practitioner for proper examination . Doctor may order urine test , blood test , along with physical examination , ECG and check vitals . Doctor may refer you to
endocrinologist in case of in case of hormonal imbalance . For now drink plenty of water , do light exercises like brisk walking and if you are taking any medicine currently then consult with doctor who prescribed this medicine and discuss the condition , Take healthy diet like fresh fruits and green vegetables , also drink plenty of water .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
