Went on a 3 mile hike in the mountains 2 days ago. had a brief light rash on thighs with some itching. rash was red but not raised like hives, but was itchy. Over last two days has had joint pain in ankles and wrist with some swelling, and swelling is more in hands. Urinating is fine. No fever. Now right leg and wrists hurt and hurts to walk, no stiff neck but does hurt to turn neck too much. She feels she can t open mouth wide. I could not find any tick bites and denies feeling any other insect bites at the time. She will see doctor in the morning
