I suffered a good deal of back pain after a serious car wreck some years ago and the aches which went along with physical therapy post surgeries may be similar to what you experience in recently working a part of your body which has not seen a whole lot of activity. In my situation, as the therapy got underway, muscles and groups of muscles which had not been used for a fair spell cried out with "Ouch, why are you doing this to me?" It is not unusual at all for such muscles to respond poorly at first when activity is renewed. The achiness went away as I continued therapy, and now those aches do not bother. They just faded away as I resumed activity.

Eating more healthily........... well, as you might imagine, being laid up for a LONG spell after that car wreck I became enormous with bulk not something I wanted to accept. SO, working with my doc and being more conscientious about eating, I have pared away calorie intake substantially. Fruits and veggies as you mention are a part of that healthy eating bit..... The immediate result? I began to notice greater hunger, because I was no longer over doing the calorie intake. The more long term result? Weight is shedding because the body does respond well to being fed properly. Goodness....... I might be able to fit some clothing which languishes in our closet unused because I had gained too much weight! How about that?

Keep up the good work, and may your day be blessed!
