hi all. So this morning, i was awoken to a lot of pressure in my head, I felt my heart rate thumping and I heard my heart beat pulsating in my right ear. It went away as soon as my heart rate went down. It scared me, and I wasn't sure how to interpret that. As I got anxious my heart rate increased and I heard it pulsating in my right ear again but not as loud. I eventually fell back asleep and woke up again to the same feeling as the first one. Both times I was in REM sleep. Oh, after the first time, right after, my right arm started to feel weird. Some areas on my skin feels tight and dry. I did injure my shoulder on Saturday and it hurts more on that area as well. I do know I haven't been hydrating very well these pass few days so I'm wondering if that's the problem. As in typing this I'm not so sure if it is pulsating tinnitus?!!?? I don't know... I do have tinnitus in general so I thought I'm starting this form of it. What do you guys think? Anyone with pulsating tinnitus experience this? Thank you!
