Patient discussion about current

Q. I am looking for help. I am diagnosed with ADHD and currently under medication. I am looking for help. I am diagnosed with ADHD and currently under medication. I often get angry for silly issues. And I hate the company of others. I don’t like anyone and sometimes feel angry but hide within me. Please help in any way. Thank you!

A. I feel that you need some additional medication to calm your anger and agitation. I think attending psychotherapy along with medications will help you more. Psychotherapy will help you learn how to plan better and how to lower the stress and anger that you frequently feel.

Q. Can any one guide me…..my wife is in trouble…please help…We are currently taking all possible tests….. hi all, my wife is diagnosed with the breast cancer and the report revealed that it has spread into the chest bone. As per my knowledge bone cancer is dangerous. Can any one guide me…..my wife is in trouble…please help…We are currently taking all possible tests…..

A. I am sorry for your wife….its really a bad time for you. Bone cancer which is the result of breast cancer is a matter of concern and is diffcult to be taken care of. But the chemotherapy, surgery and radiation treatments are very potent to control the spread of cancer to bone from breast. You must get your tests done first and do check for the symptoms of regular cough, breath shortness and chest infections. All this indicates the requirement for the quick treatment. Don’t worry …..everything will be fine.
