Help me get a MRI scan

Hiya, I am needing money to help pay for a private MRI scan as I have clots in my legs witch are visible, pains in my abdomen, under my ribs & tingling in my head & neck & tight feeling around my right knee & right fore arm, my skin burns & flacks off. My bones are constantly aching. I really leave the house as I can't walk far due to back problems, iv already battled serve depression & anxiety. I don't want to go down the same root again, this is all due to getting knocked over afew years ago by a hit & run driver, I got back up on to my feet & never went to hospital witch I regret now. The doctors are telling me it's all in my head when I no I am in agony. They fob me of all the time. I would love to do more things with my 9 year old son please help me. Any donations would be greatfully appreciated. I just hope it's not cancer and it asnt spread fingers crossed.
