Hello, As most teachers are having similar complains about the back pain, knee pain, legs pain and radiating pain in the upper limb. These symptoms are related to the job profile. As teachers have to stand longer, teachers have no proper physical health care, always tensions and troubles etc. The reason for the pain in knees are due to early OA changes in the knee joint, and the leg pain is added to the standing for the long run. Pain in the middle finger is the reason due to cervical spine disc nerve root entrapment due to postural changes. I will advise for doing regular exercise which includes the strengthening of the neck muscles, upper limb muscles, inter-scapular muscle, knee muscles, leg muscles, hip muscles, core muscles etc. As these muscles are used in a wrong posture and repetitive stress injury is occurred to the tissues, joints and ligaments. Taking utmost care is important from now as most people ignore these symptoms and when the symptoms boom up it may lead to pain and aches to the maximum. None of the students is having a sense of respecting the teachers. But it s sad that most of our teachers s are suffering from the same issues and there is not much help from any student. I will request you to take care of your health and get selfish for it because we need teachers like you who have shaped the world of today. I salute you for being a great mentor to the community through it s unheard and ignored by others. Hope I have answered your query. Let me know if I can assist you further.
