karthi3219 Hi!
Sorry to read you are in pain and wish I'll be able to help somehow.
From my experience, any wireless frequencies emitted with enough energy might interfere with your body over an extended length of time. Contrary to the popular belief, it doesn't have to be ionizing to be harmful. The difference is, ionizing is most likely harmful over a very short period of time, where as non-ionizing is most likely harmful over a very long period of time (often longer than the length of the studies claiming the opposite). And "harmful" doesn't necessarily mean "cancer". The list of health effects is pretty exhaustive. Also, not everybody is affected the same way. It very often depends on your lifestyle and if you were blessed with good genetics or not.
That being said, I tried to help somebody else on this forum. Here is the link to my post if you are interested to read, down below. The only sensible way to be able identify your problem is to measure it. Unless you are actually taking measures, it's just guess work, which won't help you solve anything efficiently.
There you go. Feel free to ask questions if you need more clarity.
