Sudden pain and swelling around your toenail without an injury often points to a localized skin infection called paronychia, sometimes caused by an ingrown nail. Crocin (paracetamol) is a suitable choice to help manage the pain and reduce discomfort. Soframycin (framycetin) is a topical antibiotic that can help if the infection is very superficial. However, if the swelling is severe, throbbing, or spreading, you may need prescription oral antibiotics. I recommend keeping the foot clean, soaking it in warm water, and having a healthcare professional examine it to ensure you get the most effective treatment.
