<s>[INST] i had one (1) SI Injection for lower back stiffness and pain 6 days ago. it is one of series of three. the next one is to be injected on August 20th. my question is about the drug piroxicam, i was taken it up to four days before the injection then i had to stop for the injection. my i now resume the medication until four days before the next injection. [/INST] Hello, I have studied your case. You can hold proximal and start after taking injection. Physiotherapist will help you better to learn more exercises in proper protocol. If required intra-articular injection can be given. Diet rich in calcium and protein will help. Osteoporosis can be associated, so you may need to take calcium supplement. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care </s>
