2 weeks after an injection of winny in my tri my tri started to swell and its been getting worse since. it has been swollen for 2 weeks. it started swelling when i was on holiday (Greece) half way through. i can only move my arm throw half its motion becuase it hurts so bad. the swelling is not ball shaped and does not seem to be in the same place as i injected. It does not seem red but it is very hot and very hard. could this be anything to do with the injection 3/4 weeks ago ?
