Not to sure if I should call 111 or not. Heart rate. Normally 80 has gone to 160 at resting. Am quite stressed at moment. Also have PoTS. When that flares up heart rate normally dose t go above 120. Am light headed have fainted once feel faint. And have bad palpatations. But I have DCs at home, I hate doctors am at a loss really. But not to sure if doctors needed for heart rate (hence AIBU) don't no what to do.
