The last week or so, i have been waking up with both arms and legs feeling like I've worked out for 24 hours straight. I haven't changed my daily habits and the only thing that makes the ache diminish is taking Tylenol. I'm eating, drinking lots of water daily and walking 3 or 4 times a week. The only thing I have changed in my diet is I bought a different type of Fish Oil that I take once a day? Thank You!
