So I ve been home 5 days and the swelling has not gone done, it itches and sore to the touch. Should i go have it looked at now or wait.

Hello, Thanks for your query. I am happy to help you here. Today is 22nd of July. If you have swelling till today, then it's better to have a follow-up. Usually snakes are non poisonous. But if snakes are poisonous usually its either cardio toxic or neurotoxic & sometimes both. Swelling doe snot confirms that the snake was toxic, but it needs attention further. Although it's rare that toxin will show its action after 15 days but until the swelling subsides u need to be kept on watch. 4 views of antivenom may not be sufficient if knowledgeable symptoms appear, & if no symptoms appear, you may not need anti venom at all, but for that you should be kept in watch for at least three days. Even if just swelling appears its considered safe to administer antivenom, some patient body react to antivenom and can't be continued further. I don't think you are in trouble of having activation of toxin but still you should keep watch on yourself for following things until the swelling subsides.1) If either or both eyelids starts Chat Doctor. 2) or if you develop numbness (decrease/loss of sensation on touch.) 3)Any kind of unnatural bleeding from nose or in stool etc. If any of above complaints develop then It's must revisit ER. At the time being I recommend you to take antibiotics and anti-inflammatory medication to prevent infection, decrease itching and to decrease the swelling. For now, I suggest you to either have a follow-up or you can take some medications as bellow. Chymoral forte once died before food for 1 wk (it will help to decrease swelling)Tab Exocet 5 mg 1 at night before sleep for 3 days (to decrease itching)Tab metronidazole 400 mg thrice daily for 5 days. Tab definite 200 mg twice daily for 3 days. I hope my talk would be helpful. Will be happy to help you father. Thank you.
