Talk to Orthopedic Surgeon on Back Pain

I slipped on stairs a couple of years ago and severely hit on my left hip. I went to the doctor and after checking up he prescribed a dose of medicine and said there's nothing to worry about it's not serious. It took me a month to recover of that pain. And then in covid i got caught typhoid and took approx 6 months to recover. I am a bit healthy so joined a gym to loss weight and lost 20 kgs but one day in a gym while exercising i got pain at my back. I was going to gym before covid as well but there's no serious pain i had ever felt. But after typhoid it all started during the gym training. I left the gym and never joined again. But this back pain at my left side along my backbone start aching severely if i drink cold water or bend down. Its consistent now. Sometimes less and sometimes severe as it's severe these days. It could hardly move al.
