text: Hello..Visit your doctor again..If you suffer in general fron Panic attacks or Generalized Anxiety disorder it is supposed that you have undergone some adequate cure. If that happened all of a sudden it is more probable to be a post-traumetic stress,associated with panic and anxiety..For that condition the best temporarily used medications are Xanax and Valium(Xanax is better). You should visit a good shrink to prescribe you the proper cure that have to include a SSRI antidepressant(Zoloft works fine) and He/She could add you an anxiolitic drug,like Xanax. Propranolol in general is not well tolerated by the patient and I would not prescribe it..Anyway,your feeling of pressure on your chest can be a side effect of the Propranolol intake..If you feel still unsure contact me..Good luck!!
