My boyfriend woke up the other day with a bad toe ache for no apparent reason, he's also been feeling gross in his stomach and he's been feeling foggy headed and he still been really tiredness. Night before last the pain spread to is ankle. I'm assuming the worst thinking it's cancer. We are in an LDR and we are both still in high school and we only get to see each other once a year. Does anyone have any idea what this could be?
