I feel lightheaded for two days straight, when I lay down I feel a bit better but still same condition. My balance is unsteady, on the first day I felt like fainting, I was shaking but not because of chills or feeling cold , my head feels heavy as if someone gave me morphine. on the second day I feel dizzy and weak, and same thing and I don t have a temperature..
Hello ! I read your question and understand your concern. In my opinion the troubles you have may be related to low blood pressure, orthostatic hypotension or anemia. I would recommend measuring your blood pressure in sitting position and in stand up position. A Chat Doctor.  I would recommend also a full blood work to rule out anemia. If all the above tests are ok, I would advise a thyroid hormone analysis. A hypothyroidism and a hyperthyroidism can cause similar symptoms. If the problem persist a neurological consult and examination would be necessary to rule out any neurological problems.  Hope to have been helpful. Thank you for using Chat Doctor! Greetings,
