Hello doctors, I have only one question that I wanted to ask before. So the question is I feel little tired and facing balance problems. My left arm pain sometimes and severe for a sec and left side headache in morning n in day most of time. I can?t focus so easily I mean concentrate. I have done eye checkup everything is normal but still blurred vision I face. heaviness felling inside and sleepy. Sometime I feel breathing problem also n emotional for mo reason. Is it normal or should I go to doctor. I don?t understand.
