Hello doctor, My daughter age is 3.5year old. She has fever on 28th July morning and suddenly in afternoon her voice has changed like gala baitha hua ho. She is complaining for blocked nose. Now she has recovered from fever but still her voice is still same . I consulted with doctor and he mentioned in prescription that she is suffering from LTB. Kindly explain this and when she will be ok means her voice. Iam attaching doctor prescription for reference.
