Hello doctor, I am 36 years old and healthy. I had Vitamin D3 deficiency with back pain four years ago when I was abroad. I came back and, did physiotherapy and Ayurvedic treatment. Things got better in two years. But I still have the following symptoms. Back pain comes when sitting for a long time specifically in certain kinds of chairs. Sometimes twisting pain comes suddenly when I sit in certain chairs for long. Standing continuously in certain types of floors is an issue. Lifting weights is fine, but still, need to comfortably lift more than 6 kg. Standing is comfortable in roads, shops, etc., for a long time. Spine pain radiates to the back of the head and neck at times. When that happens I sometimes get lightheaded when seeing objects rotate. Pain comes when I sit and clean objects. If I do no fully sit pain does not come. Long scooter rides sometimes cause back pain the next day.
Hello. You have symptoms that are typical of core and back muscles weakness. I will advise you to take up some regular exercise schedule whether it is gym-based, or at home like yoga, or even at work where you do chair-based exercises that help you with core strength and back toning and flexibility exercise. You can see a good manual therapist or a physiotherapist who will be able to guide you. You should be mindful of poor posture and avoid sitting in position for any length of time.
