Hello Dear Doctor, Im Waseem from Pakistan, im myself a medical student. Sir, My problem seems unexplained. About a couple of months ago iv had some low grade fever which was persistent for a long time, soon after i started to breath difficultly, its not like i cant breath, i can but once in a couple of mins i need to take a deep breath, it feels like my chest is tight. i went to a local doctor, he suggested me that iam having allergic rhinitis or rhinosinisitis and kept me on montelukast 10 mg which i started to take from the day one, i feel a little better but the problem still persists even after 2 months. I feel sore throat and continuously clear my throat, ears feel like im havin tinnitus, once i had Cole slaw and caught 103 fever for which i took antibiotics. iv taken alot of medicines like antibiotics, anti allergic medications but the problem doesnt seem to go. Yesterday iv had milk and today im having 101 fever with worsening of breathing. More over, i take escitalopram from last couple of years about 3 mg per day but its the first time ever im going through such a problem. kindly help me out, life has become very difficult and normal things are getting harder for me. ill wait for your answer to my case. Take care
