How long till I can play rugby u got a concussion 7 weeks ago still have bad headache feel dizzy I wanna play asap I'm not doing running how long wait?

Please be patient. Seems you still possess some postconcussional symptoms, and best you not risk additional injury until all is settled down. Would very closely with neurologist or physiatrist, and get treatment for current symptoms. Likely, you will improve dramatically over next few weeks.
See below. You want to conservatively have 1 week symptom free existenence (no headache or dizziness) before playing again. Seek out your pediatrician/internist/family practitioner or a sports medicine physician/orthopedic doc or neurologist to ensure you are improving-or to attain clearance.
