Constant fingertip pain can stem from various causes, including poor circulation (like Raynaud's), nerve compression, or arthritis. For temporary relief, you can apply an over-the-counter topical anti-inflammatory gel, such as Diclofenac (Voltaren), or a capsaicin cream if the pain is joint or muscle-related. Warm compresses may also soothe the area. However, because fingertip pain can indicate underlying nerve or vascular issues, I strongly advise against long-term self-medication. Please consult a doctor for a proper physical exam to identify the exact cause and get a targeted prescription treatment.

Your symptoms of finger numbness and slowness in winter could indicate conditions like Raynaud's phenomenon or nerve compression (such as Carpal Tunnel Syndrome), which worsen in the cold. Because proper treatment depends on an exact diagnosis, please do not self-medicate. I highly recommend consulting a doctor or neurologist for a physical exam. To manage symptoms now, keep your hands warm using insulated gloves or hand warmers. If diagnosed, a doctor may prescribe vasodilators (like calcium channel blockers) for blood flow, or specific nerve medications. Prioritize getting a formal evaluation first.
