I have a pain in the higher parts of my back. I also got a high fever (but i feel cold and are freezing but also sweating like crazy) from nowhere and my heart beats fast and hard, But I take meds agains high bloodpressure and fast heartbeat so it should not be that way. I have diabethes and weigh around 170 kg, Am 207cm tall.
Hi I did review your concern. Your problem could be due to flu or systemic viral infection where in you have fever with chills, myalgia causing backache and fatigue.it will slowly regress in 2-3 days. Take a lot of water and consult doctor if fever doesn't subside with Tylenol. Wish u all the best
