I got a concussion week before last & am having a horrible time recovering. I ve been to the ER twice. I already suffer from vertigo and it made it worse. Fast forward to now... I have a constant headache, vertigo still high, although it has lessened some, nausea, vomiting, and today I noticed my eyes are red. I was prescribed zofran, meclizine, hydroxizine, & aleve. They don t seembto be working. So...my questions... are red eyes normal? and is there anything else I may try to lessen the symptoms I ve listed above?

Hi welcome to ChatDoctorI have gone through your query regarding vomiting and vertigo in a person post a concussionDizziness, nausea, headache, are other common symptom about PCS, Red eyes are not a normal symptom though, yet it is just an outcome of your prevailing problems, is not a cause of concern. Redness lie down will go automatically when you are free of principal symptoms . Meanwhile, you 1.  Wash your eyes with cold water 2.  Lie down in a comfortable position, Take cotton pad dipped in cold water, squeeze extra water and apply on your eyes.  It gives instant relief. Repeat for 4-5 times.  Resting will help prevent attacks. Lie down for a minute or two and close your eyes. This will allow more blood to flow to your brain. After lying down, sit up slowly and remain sitting for 1 to 2 minutes before slowly standing up. It is recommended that medications be avoided if possible. Especially if they are not working. Side effects of medications may affect people suffering the consequences. Do not Chat Doctor. Do not lie flat on your back. Prop yourself up slightly to relieve the spinning sensation. Move slowly to avoid the risk of falling.
