[|AI|]  Hello! Thank you for asking on Chat Doctor! I understand your concern, and would explain that your chest pain doesn't seem to be cardiac related. Is your chest pain modulated by respiration or body movements? In such a case the most probable diagnosis would be a musculoskeletal pain (possible Costco Chat Doctor. Regarding the problems with your vision during standing up, it may be related to orthostatic hypotension. You should measure your blood pressure during sitting and standing up position. If there is a decrease in your systolic blood pressure more than 20 mm Hg during standing up, compared to sitting position, this would be very indicative for orthostatic hypotension. A head up tilt test is necessary to rule in/out this disorder. I recommend consulting with the GP for a careful physical examination (including head up tilt test), a chest x-ray, a resting ECG and some blood lab tests (complete blood count, thyroid hormone levels, fasting glucose, blood electrolytes, kidney and liver function tests, inflammation tests), to exclude other disorders related to chest pain and this symptomatology. Hope to have been helpful! Best wishes,
