My husband was at his gp complaining of tiredness , nausea, headaches , sweats and lack of energy. He is otherwise very fit and healthy 49 yrs. no ph , urinalysis nad awaiting results for thyroid, LFTS CRP fasting blood glucose NAD . We are going on holiday next week abroad which deeply worries me as he is so miserable with the above complaints . Suggestions would be most appreciated Thankyou Sharon Jones
