Thanks for your query, I have gone through your query. The blocked nose and running nose can be because of allergic rhinitis or it can be secondary to the polyp in the maxillary sinus or a narrow meatal opening. Consult a good ENT surgeon and get it evaluated. You need to get a CT done to confirm the diagnosis. If there is any narrow meatal opening or a polyp you need to get it corrected surgically. Till then you can continue the same medicines. I hope I have answered your query, take care.
