I had a cold like a week ago it was a very bad one and iv still got it now. Each time I blow my nose a lot if coming away generally green thick mucus. Yesterday while blowing my nose I went extremely dizzy and fell over ! My ear was then making gurgling noises (the left one) and then last night I went to bed and woke up this morning and I can’t hear very well, my ear hurts if I swallow, does this need to be seen by a dr or is it normal after a bad cold ?
