Are you also a diabetic. If yes what are the sugar levels. Present fever
etc. are due to a chest infection
which could be viral too. Are you taking any antibiotics ?
Burning feet could be effect of some antibiotics or viral infection too. So wait till the current problem of fever and cough settles.
You blood pressure is also very uncontrolled and you need to increase the doses of your BP medicines.
Medicines used for cough and cold
also sometime raise the blood pressure specially in previously hypertensive subjects.
