ohh dear you must be feeling awful!!!!
Anyways you havent mentioned you age,That would be helful from my point of view but no worries.
I would suggest to test your blood sugar levels from some authentic place or just by a glucometer first,to be sure that you are not Diabetic by any chance.
Secondly please do not apply any cream or ointment which contains Steroids
for a very l;ong time.
thirdly try to take take some oral anti fungals like Fluconazole
for example and lamisil
cream prescribed and directed by your doctor ofcourse.
Fourthly you can also add anti allergics like Tablet Piriton
4mg three to four times aday for a week or two.
i hope this will help you out.
and have a nice day.
