Hyperthyroid Patient And High BP. Slight Pain In Right Side Of Chest Radiating Towards Shoulder. Bone Protruding From Chest. Treatment?

Question: Hello Doc,
I am 33 years old. My height is 5'9''. I am a Hyper thyroid patient for last few years with thyroid under control with medication (Carbimazole 10 Mg per day).

In April 2013, my Endocrinologist said I have high BP with upper reading to be 140 and advised me to start having morning walks. Although when I got it checked somewhere else twice I found the BP to be normal. Anyways, I started morning walks. But then I thought I am a bit overweight so I started jogging as well. Earlier my weight was 80.5 Kg and now after 5 months of walk and jog I managed to reduce 3 Kg and now weigh 77 Kg.

In July i.e. 2 months after starting the walk/jog I felt slight pain in right side of my chest radiating to my shoulder. This was more during night especially when I turned sides while sleeping. And during similar time frame I realized I have a hard bone protruding from chest just below the collar bone (just right side of center). I showed it to an Orthopaedician and he said its nothing because it didn't pain when he touched the bone. He gave me some tablets to take care of any inflammation in the bone and also gave muscle relaxant for a week. It all was good for a 10 days but then the pain returned. I think there is some relation between this slight pain (may be muscular pain) I experience on right side of chest and this bony bump. I normally do not experience any pain in this bump or in chest during daytime while sitting or walking. Although while breathing deep I do feel a little sensation in chest.

Can you please help me understand what it is? Is this bump and pain are related? Can it be something serious? I am still jogging and doing light exercises in the park (I do not go to Gym).

Thanks
