Hi,
Your heart rate sounds like it is an appropriate response to activity and I would expect it to be about that fast depending on your activity. As long as you are not having any chest pain,
lightheadedness, or passing out, I don't think there's anything to be concerned about.
This can also be affected by your fitness level, which your
shortness of breath may be related to as well.
Acid reflux can be exacerbated by the foods that you eat, including spicy foods, caffeine, citrus fruit, and chocolate. Avoiding any of these may help.
You can also try elevating the head of your bed to help prevent the reflex of acid in your stomach. Avoiding meals too late at night can also help.
Muscle cramps can have many causes, including
dehydration and electrolyte abnormalities, so I would recommend staying well hydrated and if it persists, getting your blood check to make sure your electrolytes are normal.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Aaron Branch,
