Be sure to get things checked anyway.
I had extreme back pains for ages, and the only thing that helped was smoking a lot of weed. Got rid of most of the pains, however many years later it was discovered that I had twisted discs in my spine, and the weed was masking the severity due to the pain relief!
So now I have a diagnosed bad back and I smoke a lot of weed on prescription. So... Nothing has really changed but... I mean....
I forgot where I was going with this. See a doctor! It won- I mean, it sometimes doesn't waste time. Erm.
