<s>[INST] I woke up 2 weeks ago and my back was hurting so bad I had a hard time standing walking or sitting couldn t bend or twist. It s been 2 weeks now and my back still hurts but it has been feeling a little better as to walking and some what bending and twisting. Now I noticed my lower back is splotchy and in center looks yellowish brown and 1 spot that looks like could be a bite. What is the issue and what do I do [/INST] HIWell come to HCMBackache could be due to spinal condition and this could be spondylitis, disc degenerative disease, muscular spasm, but yellow brown area could be different one and this may not be related with backache and if this need to be ruled out then clinical examination is the only option you have, for the pain you can try "Tab Diclofenac 50 mg sustain release once in day" hope this information helps, take care. </s>
