You can heal yourself, but it's not going to happen overnight. It requires a lot of persistent and dedicated work every single day. A full Magickal working takes 40 days, but that might need to be repeated if problems are more severe.
In my opinion, you should first start with building your own Aura of Protection, then empowering yourself while also cleaning your Aura, Soul, and Chakras, and only then try some serious healing. Aura of Protection; Aura Cleaning; Chakra Cleaning; and Soul Cleaning are to be done every single day, regardless of other more specific workings, such as healing.
Vibrations are powerful things - doing some Rune work can also help.
This is nothing to rush into. You should read the information on the sites to get a good knowledge, and eventual understanding, of things. Mental preparedness - which includes knowledge and understanding of Magick and Spirituality, as well as getting into the right frame of mind for doing workings and meditations - is important.
Eventually - not immediately, but eventually, somewhere down the line - you could start to ween yourself off your pain tablets very slowly. Only you will know when the right time for that is.
