Too much physical activity this weekend/today...now so sore...there!!!

My family spent the day together Saturday at our local zoo and did tons of walking, then Sunday and most of today we were busy as my 2 year old son was admitted to the hospital for dehydration after succumbing to viral gastroenteritis. We were discharged about an hour ago and are home safe and sound. To say I am sore, swollen, and exhausted is an understatement. I’m beside myself with tiredness and honestly I’m emotionally pretty drained. 18+3 with baby #2. I have an old tear from when I had my son that didn’t heal right and gets sore/irritated at times. I’m wondering if there’s anything I should do or watch for. I’m calling in again tomorrow for work. I have no bleeding or cramping. Just pain literally in my vagina and perineum, not to mention some edema in my calves and ankles.
