Last Sunday (5 days ago) I ran my first long run (9k) after running the MK 10k a couple of weeks ago. The run was fine, but I felt some tightness in my right groin immediately afterwards. Stupidly I neglected to ice it over the next couple of days, but I did avoid my normal Tuesday night run.
By Thursday (yesterday) I was feeling OK again, so I went for a short 3.5k run. Again, the run was fine but the tightness returned as soon as I stopped. This time I have been icing it.
My questions are: should I be waiting longer before I start running again, even if the tightness is not present? Is it OK to run if I feel up to it, as long as I ice afterwards?
I'm training for the Bupa London 10000, so don't want to be out for long, but am a bit nervous after reading some groin horror stories on here.
Apologies for the slightly noob question, but I'm relatively new to running, and have been lucky with injuries so far.
EDIT: I should have said that I do stretch after runs.
