Hi I'm 15 and in the past few weeks I have had pretty bad back pains whenever I bend forward or backward, lay down, yawn, or work out for just a little while. The pain is located mostly on my lower back & in between my shoulder blades at different times. Along with this, I have been experiencing hip pains when I run and sometimes when I'm walking. I started on accutane about a month ago and think these things might be related, but I would like clarity. Also, I am pretty active and am playing basketball for my high school team.
I think it is worth a chat with a trainer/coach to start and then a doc. It may be nothing big but it is worth keeping on top of issues to prevent it being a long-term, poss life-long issues. I know there is a lot of pressure on young athletes these days and have talked with a few parents (I'm 34 so closer to a parent but not one!) who worry a bit about long-term issues from overuse.
As for Accutane, worth mentioning to whomever you speak to. I know it has lots of side effects but can't say if it might be involved here.
Always best to see a doc, and at least have x-rays done of the lower back. There is one spinal issue that should be checked for . . . a transitional vertebra. While in many cases, a transitional vertebra doesn't cause problems, there are several variations of this, and some of them can cause problems. It is also known as Bertolotti's Syndrome. It's something that one is born with. I was born with this. I have 6 lumbar vertebra and only 4 sacral vertebra. I also have what is known as a 'false joint' on the right side of my transitional vertebra that is not fuse to the sacrum. Basically, the right side of the vertebra tried to fuse with the sacrum, but didn't. I was a gymnast in high school, and this was one of the worst things I could have done. I didn't know about it at the time though. This is something that will show on an x-ray. If you do see a doc, and have x-rays done, be sure the doc actually looks at them with you!
A GOOD chiropractor would also be able to do x-rays and look them over with you and point out if you have the transitional vertebra. It's hard to find a good chiropractor though.
Good luck with things and let us know what you find out!
