No, you are not alone. Zuzu. Did you know the simple task of raking is considered one of the most energy-using activities in the yard? As much as we love gardening it is hard work! Spring time awakens muscles we haven't used much in the previous winter. And sometimes those muscles are not happy about it at all. Stretching before you go outside to play helps. I take 2 ibuprofen (Motrin, Advil, etc) before I go out. I usually work 4 hours at a time. so after my shower I take 2 or 3 more ibuprofen. That and a good night's sleep seems to squelch the inflammation enough so I can at least move the next day. The stiffness the next day, however, I haven't been able to conquer except for going right back out and go at it again. But that only adds to what I have already strained. It's a vicious circle. I would gladly appreciate any hints for that.
