<s>[INST] I ve been having anxiety for the past 7 months and recently I ve been getting mild headaches and weird sensations all over my head. I also get these weird feelings like numb-like waves that happen only for like 2 seconds. I also have tension around my neck and back/chest on the left side of my body. I really hope it s nothing really serious... [/INST] earWe understand your concernsI went through your details. I suggest you not to worry much. I sincerely opine that these could be signs of anxiety and apprehension. These could arise out of obsession also. You had that disturbing sensation once. You expected it to happen again and tried. Then you started experiencing it as you were expecting it. Then your body brought the familiar symptom because you are expecting it. Then you started worrying that the symptom is coming again and again and expect it. Body brings it again as you are expecting it. You become worried and so on. That is obsession in simple terms. Ignore it and the problem vanishes. I sincerely think, you need expert medical / psychological advise. Please consult a psychologist.If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further.Hope this answers your query. Available for further clarifications.Good luck. </s>
