 [ Symptoms ] can this these dots be herpes hpv syphillis or some type of std [ Disease ] it is entirely possible that the liquid you are referring to is in fact stomach acid it is not uncommon for reflux to get worse when lying down did your doctor prescribe something for you to take for the acid reflux if so and it is not working then i would suggest you return to the doctor to describe what is going on he or she may want to change your medication or have you try a mechanical approach to the problem such as elevating the head of your bed on a couple of bricks you also would be well advised to stop eating within two hours of bedtime i doubt the symptoms you are describing are related to any heart problem but only your doctor can say for sure no matter what this issue is having a negative impact on your daily life so you should get it checked out again best wishes to you
