I had a head injury five years ago and started suffering

Hi, I had a head injury five years ago and started suffering with symptoms since including unexplained weight gain, fatigue, poor sleeping at night, hair loss, bruising easily, rounded face and hump around the upper back. My cortisol levels were tested and were high above normal range and was told to de stress my life. Did so, I tried I’m unable to work. I spend most days resting for the last five years which haven’t changed my symptoms. I’m now very poorly where I’m suffering permanently with pressure around the head or chest pains everyday whenever I get up to do something. Don’t know where to turn as when I get tested at a&e they check my heart rate and say is fine and send me away. Help
Assistant: How long have you been dealing with this? Is there anything in particular that makes your head feel worse or better?
Customer: No not currently
Assistant: Anything else in your medical history you think the doctor should know?
Customer: I had a Low-dose dexamethasone suppression test which reduced cortisol but have had cortisol blood tests done over the years and they have been high. And my symptoms are debilitating and not going away. I now feel I’m likely to either have a stroke or heart attack with my present symptoms so I test all the time.
