I always find that a trip to the Osteopath always sorts me out. I am always amazed how I'll go in there with a sore leg and discover that I've actually injured a hip!
My other favourite alternative therapy I swear by is acupuncture - but generally I need a few sessions to get the benefit (so can be quite expensive) whereas I usually just need one trip to the osteo and I feel 250% better immediately.
I hope your back continues to improve.
And even if you have any concerns about your health at all, by all means get it checked and double and even triple checked. Don't worry if the doctor thinks you're worrying unnecessarily - do you what you need to do to get peace of mind.
Just keep moving! And don't be lazy...
