My mother had acute stroke one month ago, she has been on medication since then with deplatt 75 for blood thinning. Her bp is 138/80 And sugar 173 Her numbness in left hand and leg had stopped after hospitalisation. But it has mildly arised again from last week. Also she feels tightness on her left knee unable to do movement at times. Kindly suggest what could be the possible reason or what can be done to stop this.
