    public List<SelectOption> sOptions {get;set;}
    public List<String> myString1 {get;set;}
    public List<String> myString2 {get;set;}
    String fieldname;
    String objectname;

    public getSpecialitiesForSelection(){
        sOptions = new List<SelectOption>();
        myString1 = new List<String>();
        myString2 = new List<String>();
        Schema.DescribeFieldResult f = Schema.sObjectType.Account.fields.Specialty_1_vod__c;
        system.debug('Printing specialty values' + f);
        objectname ='Accounts';
        fieldname ='Specialty_1_vod__c';
        for(Schema.PickListEntry p : f.getPicklistValues()){
            sOptions.add(new SelectOption(p.getValue(), p.getLabel()));

        Schema.DescribeFieldResult f1 = Schema.sObjectType.Account.fields.Specialty_2_vod__c;
        objectname ='Accounts';
        fieldname = 'Specialty_2_vod__c';
        for(Schema.PickListEntry p1 : f1.getPicklistValues()){
            sOptions.add(new SelectOption(p1.getValue(), p1.getLabel()));

Possible Suggestion/Solution #1

Your code that builds the list of selectOptions is fine, but never gets called, your VF page accesses sOptions, but nothing has set that until getSpecialitiesForSection() has run, change your apex code to

public class  getSpecialitiesForSelection {

    public list<SelectOption> getsOptions() {
        List<SelectOption> sOptions = new List<SelectOption> ();
        Schema.DescribeFieldResult f = Schema.sObjectType.Account.fields.Industry;
        for(Schema.PickListEntry p : f.getPicklistValues()) {
            sOptions.add(new SelectOption(p.getValue(), p.getLabel()));
        return sOptions;
