Recuperation?

[casimendocina]

I took up aikido a month or so ago and have been learning the basics. I can roll forwards in the required fashion on my left side, but am constantly landing on my hip first when I roll on my right side. To make a long story short, this means that the muscles in my right lower back aren't feeling too great at the moment. I had a massage today and jumped almost a mile high when the therapist first massaged that part of my back. Luckily, it's now substantially better. Next aikido training is on Friday...

so my question is any of you martial arts/gymnastics people, any thoughts on how soon I should get back into it if I am still conscious of these particular muscles? I am positive that my spine is not out of alignment/damaged, it's just the muscles which have been affected.
