Ear infection from past 3 weeks. Level?

I used my fingernail to remove wax 3 weeks before. My right ear got infected. I went to doctor he started antibiotics, nasal drops, allergic tablets. Was not feeling better.  I took ciplox ear drop without doctor's prescription. I felt okay. Again after four days thought I got cured and took headbath. From next day again I got pain in ear. I used ciplox ear drop again. But pain got severe in ear and head. I went to doctor, 3 days again he put me in antibiotic. But redness inside my ear is not reduced. My doctor gave anti allergy tablets, nasal spray saying to check my sugar and thyroid level. The pain around my ear and head is still there. How it is related to my sugar and thyroid level? I gave birth to baby girl 3 months before and breastfeeding. Please tell me what can i do. Very much worried.
