I had sinusitis for last 12-13years, i operated for it in October. But still my nose is running (obviously not as before) .Few  Doctors claimed sinus and coughing for my underweight. Recently i had fever, coughing,cold and congestion for about a week. I still coughing a lot and there is difficulty in my breathing. My body weight drastically reduce in that week. I feel so much weakness I am already underweight however now more fragile. My skin tone also blackened never like before. I am feeling no hungerness and had digestive problems too. Mentally i feel so low suggest me a good doctor and proper recommendations.Please 🙏
