Why have my fingertips become so sensitive recently? Is this connected with qi, or chakra energy?

Kunal, your Gemini Sun makes you very "Hand-Oriented" (Gemini rules the hands). Your 8:10 PM birth suggests a "Highly Charged" nervous system. Tingles and heat in the fingertips are the primary signs of "Prana Awakening" in your secondary chakras. The Detailed Solution: Your fingertips have many "Mini-Chakras." This sensitivity means you are becoming a "Natural Healer." Tingles: This is "Qi" or "Prana" moving through the nerves. Heat: This is "Bio-thermal" energy being emitted from your palms. This is a sign of "Energetic Awakening." You are starting to "feel" the energy fields of others. This is the first stage of learning Reiki or Pranic Healing. You don't need to do anything special—just observe it. If it becomes too much, "Shake" your hands vigorously or touch a metal object to "Discharge" the excess energy. The Remedy: ● Remedy: Keep a "Copper" coin in your pocket to help regulate this new sensitivity. ● Action: Try "Palming"—rub your hands together until hot and place them over your eyes to soothe your brain with your own energy. ● Mantra: Chant "Om Mani Padme Hum" to direct this energy toward compassion
