What Could Cause Imbalance Problem?

Dear Doc, I have had malaria too many times since I live near lake victoria. but Sometime 1 year ago, I had a malaria that was very different.the difference was that I was loosing balance And I could not wake up in the morning.one side of my head seemed to be pulling me down.I felt as though there was something heavy inside my head. I treated myself but I came to realize that whenever I carried something like a laptop that pulled oneside of my shoulders down,the imbalance would occur even without malaria parasite.it has made me feel scared of carrying anything that pulls my arms down.at the time it started,I had just bought a Ceragem-thermoacupreasure machine which I was using for my back(I had a smal back Injury in 2006 but the machine treated it)so I almost always feel that the machine could have brought this problem..it worries me because I dont yet know what it is.kindly advise?
