Thanks for your question on Healthcare Magic.
I can understand your concern.
You are having pin point sharp
chest pain. It is commonly seen with
costochondritis.
Since you are smoker, costochondritis can recur.
So better to quit
smoking as soon as possible.
Also get done chest
x ray to rule out lung related causes. If chest x ray is normal then costochondritis is likely cause for this.
So follow these steps for better symptomatic relief in costochondritis.
1. Avoid movements causing pain.
2. Avoid bad postures in sleep.
3. Avoid heavyweight lifting and strenuous exercise.
4. Take painkiller like
ibuprofen.
5. Apply warm water pad on affected areas.
6. Sit with proper back and chest support.
Don't worry, you will be alright with all these but first quit smoking.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
