Hello, i am almost 19 years old. and before 1 and half year during regular medical checkup doctors told me that i am suffering from MLP. They said there is left ventricle thickness. but now when i go for check up, doc told me that there is a collapse in your one heart valve and declare me a MLP patient after an echo test. at that time i wasn't felling any symptoms.
Here is some values my report showing.

Aortic Root = 21mm
Left atrium = 22mm
IV septum = 09mm
LV PW = 09mm
LVED = 41mm
LVES = 27mm
EF = 70%
F/S = 40%

NORMAL SIZED LB WITH GOOD LV SISTOLIC FUNCTION
NORMAL SIZED RA & RV
FIRST DEGREE MITRAL VALVE PROLAPSE
NORMAL OTHER VALVES
INTACT IAS & IVS
NORMAL PERICARDIUM.

My current symptoms are:
1) i am felling a fine pain in left of my heart almost every day 1 hour to 4 hour.
2) Usually i feel it when i take a deep breath.
3) some time i feel like my heart is beating very heard like jumping.
4) Does high temperature effect like here temperature goes to 45C usually.

Pleas tell me that what should i do? go to doc again or its just a usual thing.
