Hello, I am Ryan Concepcion, 26 years, male. I would like to know what could be the reasons behind my chronic lightheaded-ness (whole day), unbalanced feeling, feeling faint, cold feet, and fatigiue. I am taking Stugeron for the motion sickness, Nexium and gasmotin for my GERD and Multivitamins.. A couple of months back, I was rushed to the hospital a couple of times due to a holiday heart syndrome. I was woken up a couple of times from my sleep due to numbness in both of my hands. Sometimes its just my pinky, at times my whole hands, either or both of my hands. I have been feeling detached from my body, which gives me a sense of blankness in my body. I feel as if I dont have full control of my body. I am very scared that I may have cancer or some sort of terminal disease. I also do have lumps in my neck. One in about 1 cm under my chin, and another one under the right side of my jaw, 2 cm. Both are wiggly, but are fixed. My EENT told me that it is nothing to be worried about. Should I see a neuro for this? or a cancer specialist? cardio? All of my test came back normal. CBC, Holter, Stress test, abdomen ultrasound. I am happy that theyre all okay, but none of these test are invasive or aggressive enough to have an in depth look on my body. I just hope that my unbalanced feeling could just be due to some sort of problem in my eyes or ears. Im afraid of having cancer since my mom had one before. Thanks for your time. God bless.
