Theres not alot you can do apart from continue as you are, i did mine last season and it took about 6weeks before it felt 100% better, the main difficulty i found was being able to take in a full breath rather than the actual pain!
Try a painkiller with codeine in it (co-codamol is one) dosing...
Lindfield FC are more likely the 'main' one, the first team won the mid sussex premier (giving us a good hiding along the way!), the club run 5 sides so regardless of ability im sure they would have a team to suit - the contact info is on the football mitoo site above
