Hi all, I've browsed this forum many times whenever i start to get anxious about one thing or another, but this is my first post.
For a long while now (over 6 months I've had a really mild back pain that is more or less unnoticeable throughout the day unless i really focused on the source, but could get notably painful when maintaining a straight seated position or lying down flat on my back. the pain would soon dissipate after a while of lying in the position. Yesterday however, i was sitting down as i normal and felt a shooting pain in the lower right side of my back, which felt unrelated to the original back pain that i occasionally feel which is more centered in my lower back. the shooting pain then began to recur every 10 -20 mins, not getting any worse in particular, and lasting only a couple of seconds each time, but still noticeable. the only trigger i can think of that could have started this may have been earlier in the day as i was on my way to the tube station i skipped a few stairs and landed heavily on one foot, but i'm not too sure how big an impact that could have had. the only thing i can compare this pain to is sort of like the feeling of a trapped nerve. this has got me even more worried as i have read, mostly from the internet (i know, very dumb of me,) about how progressively worsening back pain can be a sign of something serious. my only problem with this is that this back pain does not feel related to the original back pain, which hasn't gotten any worse for as long as i can remember. This isn't the first time I've lost sanity over HA/ General Anxiety either. a few months back i had a scare due to some palpable lymph nodes in my neck which doctors have said are nothing after bloodwork and an ultrasound scan. during this time i also sweated during the night which only added to my anxiety. after i got over the problem the night sweating stopped again, until i started worrying about my back does anyone get night sweats triggered by anxiety? this is also a worry but i only really sweat at night when i find myself in stress about something so i tell myself that it's due to the panic and anxiety, but would really want to hear for you guys on that as well.

sorry for the massive wall of text but this issue has been plaguing me for a while now and with the new sudden pains i got yesterday the anxiety has only gotten worse. would really like to hear what people have to say on the matter. thanks.
