Hello,
You want to know the cause of your discomfort. Here are a few:-
1. Sharp pain &
tingling sensation at the back of the head is commonly due to injuries or damage to the nerves that are responsible for sensation responses to the head(Neurodegenerative condition).
2. Toxicity developing due to
drug abuse, tobacco, alcohol, etc.
3. Certain medications like anticonvulsants &
Chemotherapy drugs can cause similar side effects.
4. Sinusitis, Migraines, Stress, Autoimmune diseases(MS, RA,
Fibromyalgia, etc.)
5. High BP, Poor posture, Electrolyte imbalances &
vitamin B12 deficiency.
You are suggested to get physically examined, get all required blood tests & Imaging tests done. Your treatment will depend upon the disease detected & its severity.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
