<s>[INST] Thank you kindly for taking my call  :)Due to the sharp stabbing pains I have in my outer perimeter of my rib-cage right next to my sternum and breastbone on my right side, I feel it's possible that I may have costochondritis. The pain is only sharp at that location and it is intermittent. It is aggravated by breathing deeply and when it comes on, it feels like the cartilage is moving and twinges due to the movement of my lungs.However, I also feel dull aches at the back of my ribs in the right side mid-back region….and feel malaise as well.I only have access to a skilled pharmacist right now, as I'm not anywhere near a doctor at this time. However, I was wondering if there is any antibiotics I could take to quell the symptoms, as I'm wondering if this is a fungal/bacterial infection where antibiotics could possibly help?Thank you so much for your time :)Mark [/INST] Thanks for your question on Health Care Magic. I can understand your concern. Yes, possibility of costochondritis is more. And in this antibiotics are not helpful. You need to take follow these steps for better symptomatic relief. 1. Avoid heavyweight lifting and strenuous exercise. 2. Avoid movements causing pain. 3. Avoid bad postures in sleep. 4. Take painkiller and muscle relaxant drugs. 5. Apply warm water pad on affected areas. You will mostly improve in 5-7 days, if not improving then get done chest x ray to rule out internal pathology. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
