Cold: Doesn't sound like a cold. Viral rhinitis, the common cold, is self-limiting and does last as long as you have it. You might have another health condition, and need further evaluation by a physician.

Cold: It’s unlikely to be a viral "cold" infection lasting three months and having no fever. We don’t have any other medical history to go on. It’s more likely allergies. Try OTC anti-histamines and if no improvement, see a doctor for work-up.
