Loop Inside Of A Cursor

I have a loop(while) statement I need to run inside a cursor statement. The loop creates records based on a frequency. The cursor and the loop work but the problem is that the cursor only reads the first record, runs the loop, but then ends. I am pasting the code below. Any help appreciated

declare dbcursor cursor for select uniq_id,account_id,created_by,encounter_id, start_date,date_stopped,sig_codes, ndc_id,modified_by from patient_medication where convert(datetime,start_date) = '10/20/2000' and date_stopped is not null
open dbcursor fetch next from dbcursor into @uniqid,@account_id,@createid,@entcid, @sdate, @edate ,@sig_code, @ndcid, @modid
while (@@FETCH_STATUS <> -1)
begin
select @freq = SIG.sig_frequency FROM SIG where SIG.SIG_KEY = @sig_code
set @hfreq = @freq if @freq = 9 set @freq = 1 set @nodays = datediff(day, @sdate - 1, @edate)
while @cnter < @nodays
begin
while @fcnter < @freq + 1 begin insert into PATIENT_MEDICATION_DISPERSAL_ (uniq_id,account_id, occurance_id, encounter_id, ndc_id, ddate, frequency, sig_code,disp_create_id, disp_mod_id) values (@uniqid,@account_id,@fcnter, @entcid, @ndcid, @sdate, @freq, @sig_code,@createid, @modid )
set @fcnter = @fcnter + 1
set @erdate = @sdate

END
if @hfreq = 9
begin set @fcnter = 1
set @sdate = @sdate + 2
Set @cnter = @cnter + 2
end
else
begin
set @fcnter = 1
set @sdate = @sdate + 1
Set @cnter = @cnter + 1
end
end
end
close dbcursor
deallocate dbcursor
