I'm 16, and for the past weeks i have been feeling extremely tierd even though i am sleeping sufficient hours. (by the time it is mid-day i have to go back to bed because i am so exhausted). i have also got this hard painful lump at the centre of where you're hips are ( at the crotch area) which really hurts every time i touch it and is really red. i don't know what it is. 
Also thought i would mention, lately every time i go jogging or do any sort of cardio-workout i find it really hard to breath at the beggining which then becomes easier as i continue to exersise, as if my chest where closing up on me even though i am not asthmatic, and this used to never happen to me. Does anyone think i may be getting an illness of some-sort, or even know what the hard lump on my lower stomach is?
