Hi, have been taking Zoladex for 9 months. Had 2* 3 monthly injection. During last 7/8 weeks all my muscles are seizing up / extremely painful. Gone from very fit 74 year old to almost unable to get out of a chair in a few weeks. Been given the option of stopping Zoladex or managing with analgesics. Very reluctant to stop Zoladex (it is working) are there any other analgesics other than ibuprofen/paracetamol.
