Recently i have been experiencing very low energy and drowziness, with trouble focusing on things. Also i have been experiencing weird anxiety in my chest. For somewhat similar symptoms earlier (6-7months back) except the drowziness and low energy which i am experiencing this time,I had done 2d echo 6-7 months the result of which came out to be normal. Also within that period i had done ecg test 4-5 times which came out to be within normal range. But this time i am feeling a lot low on energy and constant sweaty palms and feet. What could be the possible reasons and what needs to be done. Also i had done endoscopy 2months which revelaed small ulcers in my stomach for which my medications completed 25 days ago. Could this be linked as i have somewhat cut down on my food trying to eat mote healthy foods Please guide
