"I have psoriasis arthritis"

I have had this for years now. I was on a medication but was taken off it as it was damaging my liver. The consultant at Hairmyres said that I would be put on a bio drug instead but this was weeks ago and I’m still waiting for a prescription to start this treatment and any relevant info. I’m in so much pain now as I have nothing to treat this condition. I went to the hospital at rheumatology and was given a steroid injection to reduce the inflammation. The nurse told me that the consultant had stated I needed to go on a bio treatment but not stated which one. It’s a week now and even the nurses who have been great have seemingly had no communication. I have called a few times this week but still no medication put in place. I have now had to buy a walking stick as I am struggling to walk with all the inflammation in my feet. I cannot go on much more with this pain. I can’t live on pain killers. I can’t understand why my replacement treatment has not been put in place even though I’ve been off the original medication for 2 months.
