The night of 9/11 I went to bed like any normal night, nothing new, nothing different. When I went to bed I rolled onto my right side for what I thought was going to be a normal sleep. About 5 minutes into my sleep I woke up to what felt like my bed was shaking. Turning out I feeling a internal shaking in my back. This sensation has been with me since. When I say "internal" I mean that I physical feel like my back is shaking, tremor-ing, or maybe twitching but none of these sensations can be seen or felt on my skin.
I have noticed though that once all these started I also had some bad back pain. The next morning I went for a walk and my whole back was just killing me throughout. So I was thinking it was related.
I know two days prior to the internal sensations I did a very hard and quick weightlifting session. I went much quicker than I normally do and probably used some back form also. Then the wednesday of I walked about my university campus for about a good 6 plus miles with a very heavy backpack on. Then I went to work where I stood for about 4 hours. So the 48 hours before the internal sensations happened I did put a lot of strain on my back.
Over the past week and a half I had had these sensations I feel like they are slowly improving (knock on wood). I dont notice them as much or I find myself searching for them when I can still. These sensations never had much of a pattern or rhythm to them. Just I have noticed s lot more tension and tightness all over my back. Sometimes I can feel the muscles knotting or turning. I had someone felt by back and they said "it feels like your muscles are doing the wave".
I get other weird sensations on my back also, crawling, pins/needles, buzzing... right now as I type this my back feels a bit sore and tight. I also have been suffering from a lot of lower back pain. Sometimes it hurts even when I sit down, it is constantly there when I walk.
These sensations are only present in my back, i have felt them no where else in my body.
I have been on no new medications and live a pretty stress free life. Although i am aware these things could be stress related.
So is there a chance I could hear why i have been having these internal shaking sensations in my back?
