Methylcobalamin (often 1000 mcg) can be taken safely in many cases and may help if your symptoms are due to vitamin B12 deficiency, which can sometimes contribute to nerve issues and low mood. However, it is not a primary treatment for depression or tinnitus unless a deficiency is confirmed. It?s better to check your B12 levels and consult a doctor before starting, so you get the right treatment for the actual cause.

Your current medications (Topaz and Tryptomer) are preventatives that require time or dose adjustments to work effectively. Since your pain is currently unbearable, please consult your neurologist. They may temporarily add a muscle relaxant (like Tizanidine) or an anti-inflammatory medication (like Naproxen) to provide immediate relief. Because sitting triggers your neck pain and headaches, it could be related to nerve compression or muscle strain in the neck. Do not self-medicate with new drugs. Instead, ask your doctor about physical therapy, posture correction, and ergonomics, which are highly effective for this specific type of pain.
