Lower Back Pain

Here is my issue (may be you experienced something like that):
I’m experiencing pain, burning sensation and heaviness on lower back side and all this started with indigestion(acid reflux) . Initially, I had swelling too on my lower back which went away. This pain is not there all the time…but I have seen a correlation with erection which means that when I have erection, I feel a tightness on lower back side and pain as well. I’m also having constipation issues.

Past:
I took fin in 2010 for 10 days (0.5 mg) and had experienced similar issue in 2011 (also started with indigestion) but went away after few months when I took L-arginine. I do not want to try that again since it increased my BP and caused anxiety issues. In 2011, I got CT, blood tests, urine tests, Ultra sound, X-Ray done and finally doctor told me its muscular pain related…I still don’t believe this analysis…

Any comments or thoughts?

I also had very bad back pain while on fin. I think the only cure for this is time.

Hmm…I had no back issues while on fin for 10 days…it started after 10 months of quitting fin…
