<s>[INST] just the other day I began having severe back pain/spasms on the lower right side. I thought it had something to do with being dehydrated but not certain. I ve never had back problems but have had spasms before in the shoulders and not in the back. It s not completely debilitating but close to it. How can I treat that [/INST] Hello, Thanks for your query. Reduce the level of activity that caused the lower right back pain. Because it is in your right side, be careful not to favor your right side more than the left. This is a bad habit and will lead to more injury in the future as it creates an unnatural balance of muscle. Do not lie in bed for more than 48 hours as you will begin to weaken the muscles and increase the chances of recurring lower right back pain. Try to continue with your non-strenuous daily activities if possible. You can apply ice for the first 24 to 48 hours if there is swelling. After ice treatment, or if there is no swelling, apply heat in order to increase blood flow to the painful area. Tylenol should be your first choice for pain medication. If Tylenol is not available, try other anti-inflammatory medication. Start light stretching and exercise after a few days. If your fear of re-injury is preventing you from performing normal functions, make an appointment to see a specialist. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care </s>
