hello doctor i am 21 and lately i have been noticing that i am gaining a lot of weight .and my back bone hurts badly.. i has reached to such an extent that i even my knees hurt i cant walk up the stairs. i recently visited a gynecologist she inspected a hormonal disturbance. even though i don t eat much but i feel that i am gaining weight . i think its not the weight that i am putting on its the swelling that s causing this pain.. i am extremely upset i want to know whats happening to me.. i have noticed that my heartbeat gets really fast even when i sleep. apart from that i have an allergy and i have been having my allergy pills ..it a weird kind of allergy that causes itching all over my body and once it starts i go totally mad. i feel scared now.. i stress a lot on this almost everytime every second.
