Hi, can you please let me know what is going on with me? My entire body aches and my head feels heavy. Even my skin hurts excessively. I feel like my brain moves inside my head and when I bend down, my head feels very heavy. I am sweating excessively at nights. I feel like my entire body is wet from sweating. I do not have a fever, so I don't know what this is. I have been taking ColdFX extra strength. Please give me an indication what could be wrong. - Thank you
