Tachycardia suddenly kicked in while napping. Minimal relief after mini yoga session. Sometimes rolling on back or rhythmic exercises can help. Short of breath, distress in chest, sharp insistent ache in middle of upper back (slightly to left side). Sudden feeling of extreme heat inside head along with pressure/ache in both ears, sharp ache in right eye, nausea, dizziness, and pain in stomach. Diarrhea 20” after onset. Relief after second time. WTF. It feels like my heart had a party and forgot to invite me. Sinus tachycardia? I got sick on way to the store earlier today in a brand new vehicle from fumes (formaldehyde, industrial adhesives, plastics, etc). Thought I was going to get a full-blown migraine but seemed to recover after 40”. It feels like the lower part of my heart is sucking downward during these events. Potassium, magnesium, apple, water. Hot feeling in head, sharp quick headaches, pain in left leg (back of leg from left hip to back o f knee). No fever.
