i suffer terribly with it, and my gp, gave me predisolone tablets ( steriod tablets) 5mg....
these were used as a last resort, but the injection i have had aboad has been a steriod injection...
the tablets worked fine for me, infact they stop my holiday from being spoilt..
the chemist in
icmeler sell the same tablets, no idea on the injection..
maybe chat to your gp over here, as the injection and tablets can cause side effects,
hope this helps....
