I'm dealing with a lot of phlegm in my throat and lungs, which is making me cough a lot. I recently had laser fissurectomy and haemorrhoidopexy, and I'm already taking a lot of antibiotics. Every time I cough, it hurts, especially near the surgery area. I've been using Syp. Ascoril LS, 5ml three times a day for the past three days, and while it's helped a bit, I'm not completely better yet. Do you have any suggestions for a syrup that can help clear the phlegm and ease the cough without causing more pain?
