<s>[INST] Hello...I'm 54 y/o female. post menopause. 200lbs.  I walk a mile every day. No HBP, I take no meds. Have hx of stress/anxiety. Treat with accupuncture. My Mom had HA at age 70. I had a few twinges yesterday....worked alot in the yard. (hot day)...my heart feels tired. Felt better after sleeping last night, but still I'm concerned. [/INST] Hi,Don't worry, nothing serious.It may be caused from working much in the yard in hot weather.Take care </s>
