<s>[INST] i woke up friday morning with wat i thought was a sore back. by saturday morning the pain was horrendous everytime i breathe . i went to the hospital at 2 this morning as i couldnt breather properly and was told it was muscle strain xx the pain is there continuously but more so when i breathe x [/INST] As per the symptoms yes it looks like muscular pain only. I suggest to use hot pack on your back. This will help to relax the soft tissue at back. As well also apply pain relieving ointment for some more relief. Here since you have complained of pain mainly when you wake up in morning looks like associated with muscle catch, so I suggest you should also take muscle relaxant tablet for one or two days. You can also take painkiller if needed. In case if you have pain from your back to legs radiating along with numbness then there could be possibility of problem with your lumbosacral spine, disc, or nerves coming from these levels. For this I suggest taking MRI of back and check with orthopedic doctor. Here based on report he will suggest surgical correction in case there is major damage at spine, disc level. In case its normal or mild to moderate issue then he will ask you to take physiotherapy. For all above cases I suggest visiting physio for postural correction, spinal exercises suggestion and if needed treatment. This will help to reduce inflammation, pain, and will help to improve strength and stamina of your spine. Take care. </s>
