Suggest Treatment For Severe Headache

Hey - I am a 19 year old female and have been suffering from moderate to severe headaches
as well as being dizzy, blurred vision(close to black outs), weakness on right side of the body, and just tired so matter how much or little I sleep. I got my tonsils out in May so thought that all this would go away with that, but it didn't. I just had blood work and all came back fine. Waiting on MRI results and seeing a neurologist soon. I'm getting ready to head back to school but can't seem to shake this headache. No pain meds do the trick. I need some help!
