Montoux test redness is appearing little away from the injected point. Is this normal ?

montoux test redness is appearing little away from the injected point? Dear doctor , My son 16 month old had a montoux test 2 day back. The red spot appeared little bit away from the point where the materiel was injected instead of the exact point. Is it normal? This red spot which is very wide around 20mm can it be a false reading or my son has TB. Also today i have observed another such mark on his left leg near foot. My son has a history of double pneumonia three months back . He is fine from 1 month. Adnan

Hello Mr.Shaikh
welcome to HealthcareMagic
If the redness of Mantoux is more than 10 mm it is considered positive but please try to understand 2 things:-
1-When the a person has symptoms like loss of weight;evening fever or continuous mild fever; cough ;loss of appetite then a doctor can suspect TB
2-It can be said that a person has TB when all the test like ESR;X-ray chest sputum for AFB;IgM; are positive and the latest is TB Gold which is confirmatory these test are diagnostic of TB.Mantoux is also a supportive test but alone Mantoux cannot be considered as diagnostic of TB just for a simple reason in most of the kids who have been reactive to BCG vaccine it comes positive.I would suggest you to stay calm and then consult a Paediatrician who will guide you better.There are minimal chances that your child will have TB and if at all it is present it is easily treatable.Please do not worry and do any thing in a haste.
Thanks

A week ago I noticed a raised red bump just off the shaft of my penis inside the hair part of my genitals. I trimmed the hair and it cut the bump a little bit and some blood came out. It did not really hurt or ich at all. a couple of days later it was more pronounced and appeared to have a white head on it. I start Researching STD s and narrowed it down to either syphilis or HSV if it was an STD. While I had it my head it was just an ingrown hair or pimple it did not go away. after 4 days I decided to try to pop it. It seemed to pop like a zit and a very small amount of what seemed to be white pus came out. I dug around with some tweezers and could not find a hair. It did not cause any pain unless I push directly on it. after it pop it seemed just like a open volcano. I put some neosporin on it and the next morning it looked like it had a white top again. I left it alone that day and then the next morning the white head was gone and it looked like the volcano again. Today it was scabbed over but did not look yellowish in nature. I am concerned because I had protected sex(condom) with someone I did not know well about 50 days before this appeared. I have felt like I have been iching more then normal in my genital region since then but am not sure if that is just in my mind. even after typing this I still think it is a pimple since I could not find a hair but am still freaked out that it could be HSV. Any thoughts? I know I should just go get tested but am freaked out at the thought and just want assurances that someone thinks its not HSV.

3 days ago I received a tetanus vaccine in my upper left arm. Starting yesterday there was a nickel sized red circular spot & today it is little larger than a quarter. The discomfort in my arm has subsided dramatically, but there is heat in my arm at injection site, although both upper arms feel hot. Is this a normal reaction?

Sir, My mother is having tuberculosis and is on ATT for last 3 months. SHe took PZA for 2 months and she just stopped ethanbutol 2 days ago after taking it for 3 months. She continues taking R Cinex empty stomach. Well, she had mild fever in evenings since 2 months from correct diagnosis (mar end) and was diagnosed of TB on May 17. She had false cross results fr widal and hence was on Toxim O for 2 weeks and them changed medicine for another 2 weeks in April before we got alrmed that fever of grade 99+ still persists withs ame pattern. Post her plueral effusion on May 17, her fever subsided for 2 days and tehn rose to persistent 100- (99.6-99.8) and with ATT came back to her previous igures of 99+ (99.1-99.3). It has happened for last two weeks that her fever went away sometimes but it returns now rarely crosses 99.5. I must say fever has broken its stuborn pattern but still after 3 months of medicine, she has not out of it completely. Question: 1. Is this normal ? Add info: Her ECR was 60+ at teh tiem of diagnosis which ahs dropped to (5-6) . Her recent chest X-ray is normal.She did stop enthanbutol as advised by her doc last month and we are due next visit next week. 2. She had border line Fasting suger which have raised to 117. Is thsi side-effect fo R Cnex? As she mistakenly got tested for fasting after she took R Cnex assuming it has no effect and her sugar came out to be 135 and PP at 138. I repated the test as the range was too less, it was 117 next day comapred to 111 prior to having TB.

My mom is about 70 yrs. since past 3 - 4 years occasionally blood used to come from her mouth. Recently she consulted a doctor who advised x-ray, blood test etc. After diagnostics doctors say it is NOT a TB symptom. But doc does not say why blood comes from mouth. Doc says some abnormality in stomach as old cough is accumulated. We are not clear in understanding. What should we do?

Why would a doctor change a prescription from Xifaxin to Rifampin when it was prescribed for hapatic liver desease. Rifampin shows it can cause liver desease. We waant to help it not cause more!
