Hi there, some advice please. I do a bit of spearfishing but can no longer dive as had bad pains in head and often had quite alot of blood from my mouth. Has put me off so now just swim along the surface as not sure of reason? Tried to equalise but didnt seem to work. Do want to dive but not if i cant cure this, was scary when first happened!Went to doctors but was a waste of time. Any help appreciated. Thanks
