I most of hurt my back some how laying on the floor... about 2 or more weeks ago,, there was swelling and burseing around my lower back on my spine. I thought nothing of it..its located near the L4 & L5..besides that I dance. I do a lot of floor movements as well. I thought it would go away since a lot of other girls had a simalier bump. except the swelling got worse as I continued to do the same movemrnts I all ways do.. so I took a brake on my dancing. but now the burse has gone away and the swelling went down. but now thers a huge bulged, lump, or bump.. on my spine . rite on it not on the sides but rite on my spine I think its the L4 L5... im in a lot of pain. its really weriod cause I have a very cold feeling around my lower back near the bump. & its kinda numb on the bump.. its as big as a egg & you can see it sticking out, from the mirror. it feels hard too. it also feeling like a wet feeling.. as if water is dripping from it.. iduno blows my mind away? I have pressure in my hips. & I already have siadica..that's on my rite leg.. but now I have more pain running down my rite leg.. now ther pressure on my left side of my lower back.. when I touch the bump it aggervates it making more pain.. im also have pain run up to my neck... its basicly all over! pounding thumbing pain.. like a heart beat! I feel like I could vomit at times to.. and I kind pass out time to time I think do to the injury..it feels as if something needs to pop or crak in my back? I have not yet gone to the doctors/hospital.. I have no insurance... im hopeing the pain and the bump will go away but its been almost 3 weeks... & the pains getting more uncomfortable" all the people like friends I have showed the bump too freaked out like its pretty bad and I need a hospital..they say its not normal and that I shouldn't have such a big lump on my spin that its dangerous... im very worried but don't wanna go to hospital if its something miner..what do you think I should do? or what is it? any thing sound familier?
