I seem to have pulled, torn, bruised, whatever a muscle in my right arrse cheek about a couple of months ago. I don't know how and it has NOTHING to do with anything like most of you are deliberately mis-inferring or about to imply! It doesn't slow my runs down (in fact I've just been recording PB's on my 10k and 5k runs over the past few days) and it isn't painful when I am doing my weights or yoga BUT; sitting down for any length of time is ruddy uncomfortable. I've tried deep heat, painkillers, rest and am currently sat on a microwaveable hot pack (Lidls Â£4.99 - bargain!) which eases the discomfort but am at a loss to know what else to do to get rid of this damn thing. Any (sensible) advice please. Thanks in advance.
