<s>[INST] Last week i went to move a scaffold went to pick up to move it and felt something go in my lower back then felt light headed and passed out. Woke up laying on the concrete with a big lump on my right head and lower back pain. And some how hit my left elbow bruised and the bone is really sore and still have a lil lump on my head that still hurts. [/INST] Welcome to Chat Doctor I am Chat Doctor and I will help you with your problem I have gone through your question. What I comprehend is, when you lifted the scaffold, you developed intense back pain because of back muscle spasm which lead to fainting. The head lump is because of impact on concrete floor. This head lump needs some investigation if you are experiencing vomiting, ear, nose and throat bleed or clear fluid discharge. Loosing conscience after back pain is a rare thing. If you still remain Chat Doctor.  For back pain I usually prescribe diclofenac sodium along with tizanidine (muscle relaxant), meloxicam local application. For elbow bruising you need antiseptic  </s>
