My cough's been lingering ever since I had COVID three months ago. It comes with mucus and now isn't going away. I've tried antibiotics, anti-allergic meds, and syrups, which seemed to work while I was taking them, but the cough just keeps coming back once I stop. I've had tests like chest X-rays and RTPCRs, and everything looks fine, so that's a relief, but the cough is driving me nuts. I've been prescribed a bunch of medications like Augmentin, Levomac, and Montemac, but I don't see much improvement. I'm beginning to wonder if this is normal. Could it be some kind of long-term COVID effect or allergy issue? I'm really looking for some guidance on what steps to take next.

Yes,continue all the medications as advised by the physician.
