Having started playing again after a long long break, I'm finding the mid/upper right side of back (think it's the right rhomboid muscle) isn't enjoying this at all and I'm constantly in pain after a round of even 9 holes and having to rest up for a good 5 or 6 days before it settles back down again. Trying to get some lessons sorted as no doubt it'll be my swing mechanics causing it. Any recomendations on how to speed up the recovery time or some stretching exercises before heading out? I've been all over the internet looking for stuff but as ever online, lots of conflicting info.
