welcome to healthcaremagic,
from the description of your symptoms you could be suffering from hyperacidity
which is brought about by taking the strong antibiotics and prednisolone
. one of the side effect of prednisolone is hyperacidity and bloating
i would suggest try avoiding foods that are gasy in nature, acidic in nature, spicy in nature, oily in nature.
you should take some antiacids which will reduce the bloaty feeling and you will be able to eat better.
for the low grade fever
you need to get your blood tested if your cell line is ok as you have been taking prednisolone for sometime and it has a side effect of immunosuppression
hope to have answered your query.
wish you a quick recovery
