<s>[INST] On several occasions when the adrenalin glands kick in, I have experienced lower back pain. It doesn t last very long, but It never happened untill about a year ago. I don t have all the symptoms of Addison s disease, I do have some of them. I do have heart palpitations, but I had them checked out by a doctor and he said my heart was good. I have restless leg problems when i try to sleep. I do have muscle twitches in my eyelids and other larger muscles. After searching on the internet, I have seen where many people have the same pain during adrenalin rushes. There are alot of theories, but no one seems to know the answer. Any information would be greatly appreciated. [/INST] HIWell come to HCMI really appreciate your concern, such pain could be due to muscular spasm and nothing to take any thing with adrenaline, stress could be the reason for this,   hope this is information helps, take care and have a nice day. </s>
