Need help understanding

Hello first off sorry for grammar I have never been very good at it so my apologies here goes.

it started under a year ago I had stomach issues and the persisted to about a month ago where I got a UTI noticed blood when I peed(scary to see blood come out your penis no pain or burning sensations, I got put on antibiotics which didn't work then got put on others which worked and magically my stomach problems up and buggered off at the same time and then a few days after I stopped the antibiotics I woke up one morning with burning needle pricks all over my body and touching something with my foot felt like it was on fire and my right leg got weaker, I can still walk I just can feel it, a week later I was having on bed playing a game then I moved my right arm and a surge of pain hit my arm and what felt like a stabbing pain went down my arm to my hand which has resulted in weakness of my right arm, I can still use it normally it's just weaker I had stinging sensations on skin while laying on bed and itchiness started a few days ago while laying in bed all over my body, I have to literally wear clothes like shirt and trousers to bed to stop the itch which seems to work(yes I changed the sheets and duvet cover).

I have also been waking up with weakness and nausea until I eat something then it wears away and woke up with a twitch in my right arm it's small but there, I have no slurred speech a little bit of tension in my head(not that much) eyes are ok and cant get an erection and no numbness as far as I know, my gp did a stand up and walk and flicked my finger test and said not a common symptom of ms put in an appointment for a few weeks but my symptoms are getting slightly worse and worse or it may be my anxiety Heightening the symptom's

I just wanted to ask if anyone had issues like this or has some knowledge to what could cause this and again sorry for the bad grammer.
