It is possible your symptoms are linked to your vitamin B12 deficiency. Low B12 can affect your nerves, leading to unusual sensations or mild instability in your legs, especially during activities like walking downstairs. Your Neurobion Forte (vitamin B complex) injections are designed to help heal these nerves, and sometimes, temporary sensations can occur as they recover. However, this could also stem from simple muscle strain or joint alignment. Please be reassured that this is common and highly manageable. I recommend discussing this with your doctor to monitor your nerve recovery.

Your brief stomach ache is very unlikely to be related to the injection site and may just be a mild, temporary reaction. For your safety, always have a trained healthcare professional administer these injections into the muscle. If you notice any lasting numbness, tingling, or weakness, please let your doctor know so they can evaluate you.

Swelling in one foot with a burning sensation in both feet may occur due to nerve irritation, circulation problems, injury, or conditions such as diabetes. Keep the feet elevated while resting and avoid standing for long periods. Wearing comfortable footwear and maintaining good blood sugar control may also help. Consult a doctor for proper examination and treatment if the swelling or burning continues.

Feeling body vibrations and reduced awareness for a couple of hours may occur due to nerve-related problems, anxiety, weakness, or low blood sugar. Try to rest well, eat regular meals, and stay hydrated. Because the episodes last for a long time and affect your awareness, it is important to consult a doctor. A medical check-up can help find the exact cause and provide proper treatment.

Yes, a vitamin B12 level of 142 is quite low and can absolutely cause your severe tiredness, weakness, and body pain. B12 is essential for nerve health and energy, so a deficiency commonly leads to these symptoms. Please be reassured that this is highly treatable. Neurobion injections are very effective at restoring your B12 levels. While mild reactions like minor soreness at the injection site or mild upset stomach can occasionally happen, severe allergic reactions are extremely rare. Your doctor will guide you safely through this treatment to help you feel much better soon.
