Step-by-step explanation:
I can't really understand your English in this question.
1st reason: If you have a high temperature, it might be a sign that you are suffering from fever and other conditions.
2nd reason: If you are not feeling so well nowadays, you might be suffering from different conditions.
3rd reason: If you have change in mood/loss of sense or taste, you might not be feeling well.
If only one of the symptoms were present, it would depend if I need to go to the doctor, for example, if one of the symptoms you are suffering is flu, fever, rashes and related, you might need to see a doctor.
