आपके प्रश्नों को मैं पूरी तरह से समझ पा रहा हूं। आपकी इस समस्या को पूरी तरह से निदान करने के लिए मुझे और जानकारी की आवश्यकता होगी साथ में कुछ सामान्य टेस्ट और प्राथमिक पारिवारिक इतिहास को भी जानने की जरूरत रहेगी। आपकी दिनचर्या और अन्य आदतों को भी जानने की आवश्यकता होगी इसलिए इस समस्या की ट्रीटमेंट के लिए एक बार फोन या वीडियो कॉल के जरिए कंसल्टेशन हो सके तो ज्यादा बेहतर है। I completely understand your concern. To diagnose your problem completely, I would need more information as well as some general tests and a primary family history. Your routine and other habits will also need to be known, so for the treatment of this problem, once consultation can be done through phone or video call, it is better.

First of all get out of your misconception that injuries due to iron only threaten Tetanus. Contaminationof any breach of skin continuity may potentially infect with tetanus, may it be injuries from glass, metals, thorn pricks, animal bites, surgical procedures, cutting of the umbilical cord of the neworn etc. A course of immunization should be completed by initial 2 doses at 4 to 6 weeks interval and the next booster dose after 1 year. This gives good immunity for 5 years after which next booster should be taken.

No need

It depends on wound type

I keep repeating on this forum that if people take three doses of Inj Tetvac then they can be immunized for 5 years. For the details of Inj Tetvac schedule please consult with me on Practo. In this case you take the injection.

Not required

No need

No, every injury does not need tetenus toxoid if you have taken it within last 5 years.
