Find a Chiropractor, you may be able to get an appointment with one faster then your doctor, not to mention your doctor will refer you to a back sugeon which will mean another delay. Probably a MONTH or more.
Find a Male Chiropractor or a Large Fit female one. I am assuming you are fairly large due to your lifting so size matters in this regard.
They also have access to x-ray machines and such to do the diagnostics and are more likely be able to offer you better solutions then just pain killers.
Reason Why I recommend it is that my father burst a disk back when he was in his mid 30s and the best the Back specialist could offer was surgery and potential for not walking again. From what I have heard things really haven't changed in the past 20 years in that regard either
My father fortunately opted for the Chropractor and was able to completely avoid surgery, he works as A county inspector in Weights and Measures and works with 25 and 50lbs weights several times a week. He also is still farming (part time).
Somthing that will actually help recovery from this (not cover up the problem like tylenol) is MSM. NOW foods is a good brand and will help out a lot(I am new to Biotest and don't know if they carry any), I HAD cronic lower back pain for the past 12 years (weather I was lifting or not). The last time my back was so messed up I couldn't stand strait for about 2 days.
That night I used 2 teaspoons of MSM poweder in my protein shake, and on the following two evenings as well. My pain was gone by the 3rd night and has stayed away ever since. Not to mention my back is more solid now then it was back when I was in highschool.
