Thank you for your question . the condition you are suffering from is called postural hypertension. It results from an inadequate physiologic response to postural changes in blood pressure. Orthostatic hypotension may be acute or chronic, as well as symptomatic or asymptomatic. Common symptoms include dizziness, lightheadedness, blurred vision, weakness, fatigue, nausea, palpitations, and headache. Less common symptoms include syncope, dyspnea, chest pain, and neck and shoulder pain. Causes include dehydration or blood loss; disorders of the neurologic, cardiovascular, or endocrine systems; and several classes of medications.Treatment includes correcting reversible causes and discontinuing responsible medications, when possible. I would suggest you to go to a physician for furthur evaluation. If you are satisfied with the answer hit Thanks. Hope it was helpful.
