Try ice and maybe an anti-inflammatory like ibuprofen. For me the
jockstrap worked best--it was my friend for 2 weeks. You are right
that some soreness at this point is not unusual, and it is often on one
side. Even my doctor mentioned this. (Maybe it is because one nut
hangs higher, which is true of everybody-- I guess that keeps them from
knocking together all the time). I should say too that I had
occasional mild soreness on one side for a year afterward--it was very
mild and generally came after a particularly vigorous "night before,"
and generally lasted just the day. I suspect this is very rare--in my
case it may be because I started up again very soon after the op. I
mention it only to reassure people out there who might worry about
every lingering twinge, anticipating a lifetime of unrelenting ball
pain. The bottom line is that it never stopped me doing what I wanted,
it went away entirely after a year, and I am now nearly 8 years out
with no problems.
Maybe letting the boys loose will do the trick for you? Nowadays I
cringe when I see my denims hanging in the closet....I think it would
kill me to wear those things for even a day!
Also try alternating between ICE and a hot-pad.
