Question: Hello, I've thought I had a back issue of some sort, however, it's been pretty extreme over the last two nights. Last night, it woke me up and I felt weird, so I checked my vitals and got my EKG and I noticed my T-wave was elevated. It looked "peaky", which according to reputable sources, indicated hyperlekemia (Didn't believe it, I believe my kidney is fine). Anyway, it seemed like rotating my back clockwise helped the issue and my EKG went back to normal and I fell asleep. Didn't understand it, but anyway, it happened again tonight but this was far more severe. In addition to this slight numbness in my left arm and face and left midback, I was feeling notably nauseous and feeling weird energy over me and NOT falling asleep. I thought perhaps my spine was touching the spinal cord, causing these nausea feelings, but this time I did the exercise and didn't notice improvement took my EKG and the waveform definitely looked like an elevated T wave, just like yesterday night, but this time it looked "wide" instead of peaky, and the T was much higher than the R which was very small. BPM was 50. I remember from my reading that this differentiated it from hyperkalemia and suggested hyperacute ischemia (STEMI), and so I chewed up 350 mg of aspirin, and the nausea feeling largely subsided within a minute and the EKG went back to normal and my heart was now beating at 90 BPM (Very well could be anxiety). So, I'm a 29 male and I think I had/have a mid-back issue (Nerve pains happen on the left side as obviously caused by my back, suspect at the midpoint because it's usually sore to touch), but this seems rather peculiar. Should I see a doctor? I don't want to pay for the ER (Too poor) and it's too late for urgent care (12:39 a.m.) and I'm 29, so I'm thinking I could just be freaking out about nothing(Anxiety), but the evidence seems compelling in my mind. What are your thoughts?
I forgot to mention, when I woke up yesterday, there was pretty noticeable pain in the midback and chest which prompted the rotational back exercise. There was no super obvious 'back pain/chest pain' tonight like last night (The midback is almost always sore to touch), but the feeling of nausea and weird energy and not going to sleep despite feeling sleepy earlier made me want to check my EKG again which didn't look normal at all (ST elevated, R depressed, just like in the picture). It's always been 'normal' every time I've checked in the past.

Thank for your response. I called the doctor and I got an appointment a week from now. I was looking at the EKG webpage at http://lifeinthefastlane.com/ecg-library/st-segment/ , and looking through it, it seems that the LBBB graph most closely resembled the trace I got on my machine. I looked up the causes behind it at https://en.wikipedia.org/wiki/Left_bundle_branch_block, and it seemed peculiar that "Primary disease of the cardiac electrical conduction system" was listed among them. Interesting because I notice that the sore pain(When touched) in the particular mid-back vetebra right behind my heart (It's attached to the third rib from the bottom) is on the left side; I can elicit sore pain here when touched, or when rotating my spine in the counter clockwise direction. Is it possible that a spinal issue here could disrupt the cardiac electrical system and induce an LBBB on the EKG? Would this be something I should be concerned about? The fact the sore pain is on the left side of this one midback vertebra and the EKG graph most closely resembles the Left Bundle Branch Block, I'm thinking that it's affecting left side conduction when I'm laying down.
