I have been doing aquatic therpy for about a month now. There is a noticeable change in my muscles since starting. The are harder and tighter then they have in a while (the good kind of harder and tighter). However I still find my self feeling weak and stumbling around alot as well as a little shakey. Anyone have an idea of what might be going on or some advice, or maybe you are going through the same thing. Let me know thanks.
