I was diagonosed from typhoid. At that time one mistake was happened by nurse. She gave me injection of azithromycin 500 without dilution. I took around 15 days medicine. After that ringing in ear and back pain and pain cervical started. I felt muscle weakness. I went to neurologist and he told me that you have mild herniated disc. And I can't sit for more than 40mins continuously even after 2 months. I want to know if this is an affect of azithromycin wrong injection or medication per se or the weakness after typhoid. In fact 2 weeks ago I was walking and then it started pain in my right knee. I am streching and walking on a continuous basis to build muscles. I want to know if it is reaction of injection till. And now what should I do?
