I had a major a/p set back last March and that was the main reason it took so long to get back on track (or my state prior to March). I thought after 5 yrs that I had felt every symptom there was and that I had learned not to be afraid of the physical sensations I felt from anxiety,
I was wrong. I was just sitting there talking to my sister and out of no where a wave heat that went from top to bottom. I got extremly hot and broke out into a sweat, at one point it felt like I was on fire. Well I drove myself crazy went to the doctor got checked out and sure enough it was anxiety playing with me , he upped my meds and I started therapy and natural supp's and well I'm doing pretty well considering recent events in my life. Since, I have learned alot and feel alot more confident. Anyway I was driving myself miserable and it was the issues in my life causing physical anxiety. I started running to get rid of it, it works!
You might also consider weather or not it could be hormones? I'm sure it not anything thats worth the worry. If I were you I would wait and if you get another go get checked out it, you will probably feel really relieved and maybe feel a little silly when you leave. Either way you will know you have done everything possible to not let anxiety control you. Your stronger than you think, hang in there its not usually as bad as we think.
