My right pinky is starting to tingle as well. Thoughts? [/INST] Hello, It might be due to minor trauma or abrasion that may have gone unnoticed. As of now, you can apply ice packs for symptomatic relief. If symptoms persist, it is better to consult a physician and get evaluated. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shinas Hussain, General & Family Physician </s>
