Any time you think you may have a side effect from a drug you were given or prescribed, you should contact that physician right away. Steroid injections are commonly used to treat inflammation in joints especially the knee and shoulder joints. Most physicians only inject those joints 2-3 times before different therapies are explored. These steroid injections tend to stay in the joint and do not cause many body wide effects, especially if only given a few times per joint. Thus I would find it shocking that steroid infections into joints could be the cause of your eye problems. People that develop steroid induced cataracts are generally people that have consumed steroid pills for many years treating different autoimmune illnesses. For this reason, I think your eye issues need a fresh look (no pun intended) by an eye specialist. I suggest that you schedule an appointment with the physician that prescribed the steroid injections. Discuss other possible side effects of steroid use and other possible causes for your eye problems. You will definitely need an ophthalmologist
consultation to look closer at your eyes to determine for sure that cataracts is what you have. That way you can be sure to get a solid diagnosis and the correct treatment.
