[|Human|] I have low blood pressure that is causing a strange sensation. Limbs feel heavy, arms become tingling with pain that rolls across my shoulders into chest, back and neck. Feels like I am going to faint. I have pain in my right hip and I get leg cramps every night while lying down. My breathing is shallow and I am very tired.
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms could be related to low blood pressure or a metabolic disorder (electrolyte or hormonal imbalance). Coming to this point, I would recommend performing further tests to investigate for the possible causes: - complete blood count for anemia-blood electrolytes- vitamin D levels-thyroid hormone levels - fasting glucose-kidney and liver function tests- a resting ECG and a cardiac ultrasound-cortisol and aldosterone plasma levels to examine the Chat Doctor.  A Head Up Tilt test is also necessary to investigate for possible orthostatic hypotension. Hope you will find this answer helpful! Kind regards,
