Now that is weird indeed about your rash on that exact spot
I can't imagine how muscle tension, even inflammation would trigger that. But coincidence... i think not.
I have those tender spots too somewhere at that location, which feel, hard to say, very uneasy. I've got this with more certain locations around the fascial area, now that i think of it, sometimes i did notice that when pressing those spots i would feel uneasy, one would say that is normal, certain points in our fascial area aren't meant to be pressed, i do agree, but it gives me the same feeling as those heart arritmias, some dizziness, and the need to move or flex muscles (probably vent off muscle tensity) even sometimes, but not often, it triggers some slight tachycardia. (elevated heart rate).
This was just a thought that popped up when i was posting this, but like you said those arrhytmias might be linked somehow, compression of nerves can indeed cause the most random symptoms.
Also whenever i'm experiencing these arrhytmias, i found that the best way to calm it down, is to flex out, or go walk around to get something etc... sitting still or lying in bed is certainly no help, i have no experience with cardiac diseases etc... But this seems unlogical to me, wouldn't the best way to calm down an arrhythmia/elevated heart rate be sitting still or lying down relaxing? With me it does no good at all, physical activity makes me feel better.
Could this be because muscle tensity due to subconsciously tensing muscles while sitting still, or due to another cause, because that is the reason for those arrhytmias?
I'm no expert on this area, but i'm convinced there is a trigger for those arrhytmias, that isn't cardiovascular. Besides, we're all young people, i find it hard to believe if it would be cardiovascular.
Aside from that i noticed that my platysma is extraordinarily tense too, on my worst T side notably more than on the other side, when compared between all muscles i would say my platysma(mainly the part radiating to the shoulders, and just beneath the jawbone), SCM, masseter and auricularis anterior muscles are the most tense and painful, i'm starting to get the picture, but i feel like something is commanding those muscles to tense up all the time, especially when i'm physically relaxing and not dong physical activities. I have no idea what though.
For example this weekend i was working, painting etc outdoors(notably more physical activity than my average day), and my T was quite low throughout the day, i even woke up with relatively low T, but by the end of the day, when relaxing after relaxing for an hour or so on the couch, my T started to scream and it didn't stop anymore that evening, walking around and flexing was some relief, but it didn't get back to the point it was during the day.
It's muscle logic upside down.
Also i noticed caffeine has probably a slight diminishing effect on my T, i'm not sure about it, because physical activity and or other things happen as well during the day, but i would expect stimulants to tense up muscles even more, and constrict my blood veins, but it didn't spike my T at all, i found this quite peculiar too.
Another interesting thing that i've noticed is that about 80% of the time, when my T has a louder moment (which can last variably from 1min to a few hours, depending on the odds and whatever activity or posture i have), my jaw is clenched shut, i do this subconsciously a lot (inner stress i suppose), but when i open it up when i see that i'm clenching, my T doesn't fade notably(at least not directly, it does after a while after stretching a bit etc..), i have noticed it too many times to find it unrelated, but there is more to it than the masseter muscle. Any of you experience muscles tensing up subconsciously when T is a bit louder?
And yeah, i'm also convinced that the slight hiss is no sign of problems at all, but when i ask other people without T about it, most of them don't have that hiss,(about 90%, it might be a coincidence, but i noticed this when i randomly asked friends of mine this, i asked about 20persons, only 1 had it and 1 debatable), even when i explicitly tell them what they should hear, they hear nothing, so still i think there is something to it, i'm thinking the muscle tension or whatever the cause of the T is, it has been present latently for a very long time, and it passed a point somewhere where those signals interpreted as sound, became to noticeable to tune out completely. (same with visual snow, most people have it in a certain degree i think, and i have too, but never noticed it except when looking at a big white wall or such and thinking about it, now in the last months it did become more notable than before, because as i recall in the last half year i noticed it very frequently, i am still perfectly able to tune it out most of the time, but i'm becoming more convinced, that it did increase parallel with the T (which had a similar behavior before onset), so it might very well be related, and confirming the theory about muscle tensity etc... a bit more. In my uneducated opinion.
These are all just some thoughts, but i kept thinking about it the last few days, now that your neighbor physio mentioned those vision problems again, it made me think, and i think that visual snow, the occasional floaters, which seem to appear mostly when stressed or exhausted in my case, and the T etc... are most likely related.
Asides from that good to hear driving etc... isn't causing you pain or T spikes anymore
, i never have to drive 5hours (luckily belgium is a small country
), but lately it didn't bother me as well.
Good to hear you'r T has it's low days too
, the blood flowing your talking about, is it a sort of whooshing sound? i have this too dominantly in my worst T ear, have had this for a long time actually while doing certain movements, but lately looking to left or right or tensing muscles in the neck causes this too. Don't know if there's something to it.
Also weird that you'r T distorts sounds, i've had my T go up and down with loud noise, especially in the high tones, as well, i'm supposing it's tension in the middle ear muscles, but i'm not sure, it always calms down again quite soon Hope it calms down man!
