<s>[INST] Firstly my ankle just hurt, a couple of days later it started bruising, and now (5 days later) it is swollen (but a little above the bruising). The pain is over my whole ankle and specifically where the bruising/swelling is, it is a dull pain that is greater when I am walking and occasionally shoots up to my knee or hip. I may have sprained my ankle or it may be poison from a blister I had, any idea which? [/INST] Hello, I read carefully your query and understand your concern. The symptoms seem to be related to a sprained ankle. I suggest using anti-inflammatory medications such as Acetaminophen to relieve the pain. I also suggest using cold compresses for local application. I recommend maintaining a splint to avoid moving the ankle. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.  </s>
