Hello dear user! Thank you for using HCM for sharing your concerns! I ve gone through your query and I understand your concerns. All these symptoms you are describing are indicative for an upper respiratory infection. It may be viral or bacterial and to determine this we have to do a complete blood count to see WBC. Fever, sore throat, cough are exclusively symptoms of an infection. Palpiations and fast heart rate is normal since you have fevers. Neck ache and hardening, dizziness, light intolerance, and red spots in chest or body are rarer symptoms that indicate a more severe condition and which must be treated immediately, and this is meningitis. I don t intend to worry you, and you should not do that, but some immediate things you should do for now is: - Go to your ER and do a complete blood count and leukocytes. If your WBC are high you have to take antibiotics and better injections of through your veins for a faster healing. If nothing suspicious for bacterial infection is found then you can stay home and take there your medications as described from your family doctor. I hope you will be better soon. I wish you a good health! DR ERIOL.
