Multiple issues. Treat these problems?

Hi I have joint pains in my knees and hands, intermittent nerve vibrations/tingling through out my body and chest pain in the left side sometimes. Also, when I try to sleep, the heart starts pounding very fast and my body also starts shivering from inside and to stop that, I have to get up and sit for sometime and only then it feels better. My heart beats also feels very noticeable at all times and feel something moving inside at times . Not sure what is the problem. My ecg and troponin levels are normal and I have been taking Remyelin d and Etizola tablets for two weeks now but there is no improvement and is getting worse and is going on for more than 6 months . Can somebody please explain what could be the problem and what medication should I be taking to treat these problems? Thanks in advance for any help that I can get.
