I had a right colectomy 2 weeks ago due to Crohn's. I have been recuperating rather well and just had my post surgical follow up yesterday. My energy levels have been OK considering what my body has been through. However, today I am absolutely exhausted! I have not had a particularly strenuous day. Is it normal to have these days of extreme fatigue even though in days prior I have had more energy than I do now? Just curious. I want to sleep, sleep, sleep.
