Replying to Trampoline Question

Alright, I need to axe all you trampoline guys a question. So, I just got a new 14' trampoline and I been jumping on the thing a damn lot. The thing is that I get this massive fucking back pain from jumping on the thing alot, and it's soo bad that I cant even jump on it anymore cause my back hurts too fucking much.
I'm pretty sure I just stretched all the muscles back there, (it's in my upper back) and now everytime I jump on it I re aggravate them. Has anyone on here had a problem like this, and if so what did you do to get rid of it. Just time off from the tramp or what. I just got the thing like 2 weeks ago and before that I had'nt jumped on one for like 5 years, then I just started jumping alot everyday. Any help would be appreciated cause my back fucking hurts alot. Later.
